      Yes, the intelligence pics that proved the Soviets had missiles in Cuba were taken by U2 spy planes. They were published immediately - if you're trying to force the Russians to remove their missiles, you don't keep it a secret that you know about the missiles. You tell the world.

      In the early sixties, satellite reconaissance was primitive - it was still at the stage of ejecting the film in a little capsule to be picked up on the ground :-) Planes were getting much better material then.
      • Actually, I think the film rolls were captured in midair by aircraft. Ground (water) pickup was a fallback.

        It may sound low-tech, but to me a lot harder than what we have now with a plain old digital camera and radio transmitter. Imagine all the moving parts, all the things that could go wrong.
    • Christopher Moltisante: "You mean that was real?! I saw that movie. I thought it was bullshit."
    • The new International Spy Museum [spymuseum.org] in Washington DC has a very nice walk-through of photos taken during the Cuban Missile Crisis... 3 foot tall pictures show the (before and after) construction of facilities on the island.

      Combined with intelligence information about a shipment of material on route to Cuba made, they make a very telling case for why the blockade was ordered. My parents claim that the US was never closer to nuclear war than on that day, and the museum does a very good job of putting the story together. I'd definitely recommend a trip.

      Actually, the Corona program did use Kodak film. Due to static problems with early film (which caused arcing [kodak.com] on the exposed negatives), Kodak developed polymer-based film.

      I work in an electron microscopy lab and the film used for the EM systems is Kodak 4489 "ESTAR Thick Base" -- which means that my paychecks depend directly on something that was developed for use in space. (As a space buff -- Buran is/was the Soviet space shuttle -- I'm quite pleased with that situation.) A spinoff, as they're commonly called.

      The EM film is mounted on metal plates for exposing and when developed yields 8cmx10cm transparencies using Kodak D-19 developer. For Corona, the exposed film was placed in a reentry capsule which parachuted back to earth and was retrieved midair by a C-119 Flying Boxcar aircraft. It doesn't take that long to develop at all and can be ready for analysis the same day.

      According to the Kodak EM film page [kodak.com]:

      "KODAK Electron Micrography Film 4489 has approximately half the speed of KODAK Electron Image Film SO-163 film, but exhibits less curl and shorter pump-down times. Coated on a 7mils Estar support, KODAK Electron Microscope Film offers exceptional dimensional stability and eliminates the use of traditional glass support products."

      We are still using film because (1) electron microscopes are very expensive, so ours are from the mid-1970s, (2) it's not that easy to retrofit them, at least as far as I understand it, for full digital, and (3) it's not all that hard to put the negatives on a lightbox and shoot them with a professional digital SLR, which is how we get the images into computers for processing. And, of course, (4) digital camera technology still hasn't beat out film for quality yet, though we're hoping to get a Canon EOS-1Ds soon that will start to close the quality gap.

      (The film is kept in a vacuum once in the microscope -- something else which I'm sure was a benefit for Corona.)

      If you want to see some sample EM images taken with the Kodak film, see our lab's image gallery [wustl.edu]. Don't bother with Kodak's sample images, they suck. ;)

      I'm pretty sure that Kodak also designed the Corona camera system, though I'm not certain who the actual builder was.

      just imagine what we are capable of now right in our back yard.

      Not as much as you might imagine. A Hubble-sized telescope in orbit at Hubble's altitude, pointed straight down, can resolve down to 15 centimeters. That would be enough to tell that you drive a Honda instead of a Surburban, but it couldn't tell much beyond that.
      • Or more than you might imagine. 1m resolution is fine enough to see the lines in parking lots and count full v. empty spaces and see opened doors (not sliding van doors). What do you think something 7 times as good will show? Make and model of car, all doors, how many people, whether and what they are carrying, and if they wear glasses. You can probably tell the make of shoe someone is wearing at that resolution.

        And that's just from one frame. With multiple frames, you increase dramatically the information you have available, and you can interpolate down much finer than the camera resolution.

          Here's an older DejaView message on the topic. It addresses this very issue.

          Undergraduate physics:

          Resolving power R (resolution) of a diffraction limited telescope: R = wavelength/(2*diameter telescope)

          This means for the HST (2.4 meter) and visual wavelenght (500nm) R = 500nm/4.8m = 1*10^(-7)

          Since the Hubble is in orbit h = 680km (380 miles) high, this means it can theoretically resolve: Detail = R * h = 0.07. Thus 7cm (3 inch) details. Not enuff for reading license plates, even if someone would hold it up to the sky so we dont have inclination effects. Besides this, the best visual wavelength camera on board (the PC chip on the WFPC2 camera) UNDERsamples this signal by a factor of 2 giving an effective resolution of 14cm (1/2 feet).

          This holds only if we ignore atmospheric turbulence effects (which certainly DONT average out), the pointing instability (up to about 10mas (micro-arcseconds)) and thermal breathing (up to 10mas). This degrades the image even further. (10mas translates to about 5cm as seen from the HST)

          Furthermore, target acquisition is problematic. HST uses guide-stars, which need to be in the field of view, to lock on targets. Certainly no stars available on the face of the earth ;-p. Even then: A quote from the HST data hanbook: "It is also possible to take observations (primarily WFPC2 "snapshot" exposures) without guide stars, using only gyro pointing control. The absolute pointing accuracy using gyros is about 14" (one sigma), and the pointing drifts at a rate of 1.4 +/- 0.7 mas s**-1. "

          So, we have a 66% chance of 14" (arcseconds) acquisition accuracy. This translates to about 1400 pixels offset (if we were well sampled) on a ccd camera or 100m inaccuracy on the ground.

          Say we want a spy satellite with 1cm resolution (ignoring degrading affects) on orbit 300km high (if lower, atmospheric friction would cause it to fall back to the earth), then applying the same formulae as above we would need a telescope diameter of roughly 5 meters. (According the the space shuttle reference guide you would have to keep the payload doors open in flight to make it fit, hehehe)

          Conclusion:

          IMBO the NSA cant read license plates. The technology for space telescopes with this capability is only now being developed (look for NGST on the web) against HUGE costs, certainly not within the NSA's budget. Besides target acquisition is a severe limitation, and it's role becomes more important when the resolution increases.

            Problems with this analysis:

            1) Id doesn't take into account any electronic processing of resulting signals or using multiple images taken seconds apart to achieve higher resolution.

            2) Optical spy satellites are likely to use multiple mirrors, both to use adaptive optics to adjust for atmospheric turbulence, and to avoid the problem of fit in the shuttle payload.

            I believe it is the Keck telescope (which has adaptive optics) that has resolution sufficient to read a license plate from much higher orbits (all other caveats apply).

            A little tidbit... the Multiple-Mirror Telescope (MMT) on Mt. Hopkins, Arizona used to be (and may still be) owned by the airport. When it was built, it was built with an azimuth/elevation mount, rather than the usual polar mount, and used a computer steering system that was accurate enough to account for minute flexing in the very rigid metal frame.

            The mirrors were Air-Force surplus from the spy satellite program.

            The Air-Force used to "borrow" the scope from time to time. The Az-El mount was probably chosen to allow tracking of earth orbiting objects - Russian satellites.

            The spook folks work with very impressive technology. They are bound by the laws of physics, but they probably have engineering tricks that the public world has not heard of. Tricks in signal processing, adaptive optics in space, ultra-precision pointing, etc.

            Actually, if you just solve the problem of taking current earth borne adaptive optics telescopes into orbit, you can pretty well achieve the resolution you want.

            And then, of course, there is synthetic aperture radar. Synthetic aperture is a mathematical technique for creating a synthetic (virtual) antenna of very long length (very high resolution in one dimension) along the motion of the radar. Simple radar has, of course, much lower resolution than optics for the same size antenna, due to the much longer wavelength. But when you extend the antenna for hundreds or thousands of meters through synthetic aperture magic, that resolution gets very good.

            And then, of course, we can speculate about Lidar. I have no idea what the spooks may do with that.

            I think the problem of resolution is no longer of significance to the spook business. The bigger problems are areal coverage, data reduction and storage, and concealment.

            Well you don't need the space shuttle to get something into low earth orbit. In fact many of the commercial remote sensing satellites are fired up on rockets developed by Lockheed Martin, Orbital, etc.

            BTW, the U.S. government is currently allowing nonclassified LEO remote sensing sats of a .6 meter resolution. I would have to assume that the government has classified satellites with better resolutions.
          • If I recall correctly, current military satellites have a resolution of about 10 cm (~4 inches). Compare that to commercial satellite that have resolutions varying between 1 and 10 meters.. (Although one satellite can acheive a 66cm resolution)

        I think the practical limit for today's KH-11 and newer spysats is about 6-7 cm resolution, not enough to read a newspaper headline but definitely good enough to tell what kind of vehicle you're looking at.

        Remember, even at 100 cm resolution the IKONOS satellite is capable of showing some amazing images. Remember that IKONOS image of the North Korean rocket test facility?

        I expect within the next 4-5 years several companies will be orbiting imaging satellites capable of resolution at 100 cm resolution. It'll be nearly impossible to hid any secret activity with that type of resolution.

            If I remember correctly, the resolution of SPOT (launched by the French) had a resolution of 10 meters in general. The current Landsat has a resolution around 5 meters, if I remember correctly. For many commercial imaging satellites, very high resolution is not really necessary because they're designed to cover wide areas for environmental research.

            It was only after IKONOS became operational in the late fall of 1999 that commercial imaging satellites reached the 100 cm resolution level. You'll see a lot more 100 cm resolution imaging satellites from multiple companies in the coming years--several American and several European companies are designing such satellites now. We may see commercial imaging satellites capable of imaging down to 50 cm very soon.
      • When it comes to military and government technology, the general rule of thumb that I have heard from most millitary people I talk to is take what the public is being told is hightech, and multiply it by a factor of 10.
        • I have heard that too... from bragging GI's. Talk to someone who has some real picutre of the situation and they will tell a differant story. They have horrible problems organization and getting use out of their technology. Some companies make it past them in what they can do because companies are in it for money. Money will drive people much harder than preotecting yourself. Sure the military does have VERY high tech secrets but most of the time they arent able to mass produce anything useble out of it and end up buying their tech from companies or modifying existing products.

        Who needs the Hubble telescope? The government has the predator unmanned spy planes to take pics and send video feeds, and even shoot missiles at you. They fly high enough so you can't see them, and can't hear them. Sure, it doesn't offer the all the benefits of a satellite. But that's not the point... Plus, satellites can't launch missiles at you.

    • Indeed. Given that we can get one-meter or better spatial resolution panchromatic data from commercial sources now (http://www.digitalglobe.com/index.shtml and http://www.spaceimaging.com), one wonders what the government is up to. Now, when the multispectral resolution gets to below one-meter we'll have reason to be really excited.

      One of the later Keyhole satellites -- 11 or 12, I'm not sure which and I haven't had the time to look into it since deciding to last week -- actually is based on the Hubble design. However, the optics are not the same -- they cannot be.

      As others have said already, the primary mirror is not of the right design to look back at the Earth and actually yield the right kind of details. Hubble focuses to infinity and an earth-imaging satellite only has to focus to a distance of a few hundred miles -- the exact altitude depends on the satellite's orbit.

      Furthermore, Hubble's optics are too sensitive to be pointed at the Earth or the Moon -- both are so bright that they'd blow out the sensors.

      However, it is entirely possible for such a satellite to be launched by the Shuttle -- the size of the payload bay, don't forget, was set by a DoD request ("you set it up like this or we don't pay you to help develop it") and there were a bunch of DoD flights back in the 1980s and early 1990s. And Hubble is just about perfectly sized to fit in the bay -- it's the largest payload, physically, ever launched, I think.

      So it'd make sense that the civilian version of the KH-1x satellite in question exactly fits -- because that's the payload the shuttle was designed for. (A set payload bay size then leads to the overall size of the orbiter, which leads to the wing design, which leads to the requirements for engines, fuel, boosters, etc...)

      It also means that, since the Soviets copied the US shuttle design for Buran, ALL reusable space planes that have ever flown were designed to carry this mystery DoD payload! Even the one that's not ours! (I don't say "manned" because Buran carried no crew during its only flight.)

        The parent is wrong about several things:

        As others have said already, the primary mirror is not of the right design to look back at the Earth and actually yield the right kind of details. Hubble focuses to infinity and an earth-imaging satellite only has to focus to a distance of a few hundred miles -- the exact altitude depends on the satellite's orbit.
        HST's instruments include movable mirrors which allow one to modify the focus. They could easily focus on objects at the distance of the Earth's surface. HST has taken pictures of the Moon, [stsci.edu] which is certainly not at infinity.

        Furthermore, Hubble's optics are too sensitive to be pointed at the Earth or the Moon -- both are so bright that they'd blow out the sensors.

        Some of HST's instruments would saturate if they took exposures of the Earth through wide filters. Others would not. The HST calibration team sometimes takes exposures of the Earth or Moon to use as flatfields.

        But, yes, as many have already pointed out, HST can't take images resolving newspaper headlines.

    • There's a very good reason why you might link the ability to look way-out-there with the ability to look really-closely-down-here.

      The Hubble Space Telescope is very closely based on earlier KH-series spy sat designs. So much so that it was shipped from the manufacturer to Kennedy Space Center in a KH-11 shipping container.

      Indeed, a lot of the early gross design decisions on Hubble were subject to "anonymous" review from the relevant black agencies, and changes made appropriately.

      Call it an early example of the Peace Dividend....

  • Went to the link inside of the link (the USGS site itself) and it demands that I either use IE or Netscape -- Mozilla is not supported (apparently neither is Apple in any form). *sigh*
  • Contrary to earlier reports, NIMA is releasing virtually all of its imagery from these programs except for imagery of Israel.

    Now, I could be all suspicious, and beleive that this not showing Israel is in part so that we don't betray the fact we always knew about the Israeli nuke program, even back in its nascent stages, and look more like chumps who let Israel push us around and do the very things we claim not to tolerate from Hussein, and are pissed at North Korea about; but to do so would be paranoid and probably get pegged by the IAO as an Israel/America hating terrorist, and if there's one thing that crimps my discourse, it's thinking that I might be thought of as anti-american. (Stupid America, we suck.)
    • You're seriously going to tell me that North Korean / Iraqi Nukes = Israeli nukes? Do you really think that there's a good chance Israel would use its nukes against us?
    • US/UK/Israel/France all have an understanding.

      Since all four nations have the ability or have had the ability to photograph one another's sensitive areas, they have all agreed not to publish this information in an accurate form civilians or foriegn governments can access.

      Since Israel is a small nation with alot of military areas all over, it's one big excusion zone.

      Now then, what is the difference between Israel's nuclear program and Iran/Iraq/Libya/North Korea's nuclear program?

      Simple, Israel doesn't export nuclear technology. Israel and South Africa jointly developed atomic weapons and tested one in the South Indian Ocean (maybe). South Africa gave up it's weapons in the mid 90s and the Mossad was offing Nuclear Scientists in SA in 93-94.

      But even if one doesn't listen to the Zionist News Agencies, tell me one nation or group Israel shares technology with other then the US?

      They've done joint small-arms development with the Czechs. They's done armor and anti-tank work with Turkey. They've done MiG-21 upgrade work with Romania and other former WP MiG-21 operators. But no one, not even the most violent Israel haters has accused them of nuclear, chemical or bio weapon export.

      Yet with Libya/Iran/Iraq/North Korea/Pakistan and to some extent France and China, it's all about nuclear technology transfers for weaponizing.

      For everything Israel has done in the Middle East, or been accused of, they've not used chemical weapons. They've not fired nuclear capable ballistic missiles at 3 or 4 regional neighbors. They've not been running around trying to buy materials for nuclear devices or guns that shoot projectiles hundreds of miles.

      Syria and Egypt back in the United Arab Republic days used chemical weapons in Yemen. Iraq used them in the Iran-Iraq war. Iraq tossed FROG and SCUDs at Iran, Isreal, and Saudi Arabia. North Korea has activly tried to take-over South Korea and destabalize Japan.

      Israel doesn't have camps in the Negev for training Marxist/Republican/Maoist/Islamist/Anti-West terrorists like North Korea/Iran/Iraq/Libya have had or have.

      Umm, hello?

      If you haven't noticed, we don't publish images of military facilities in any of our allies. Israel, being one of only two examples of a free, open democracy in it's part of the world, is very definitely one such ally.

      But since you don't see any difference between a nation (like Israel or the US) which has had nukes for decades and never used them, and a nation like Iraq which has used every WMD it has ever gotten it's hands on, including against hundreds of thousands of its own people, I guess expecting you to think logically about the matter is a little much.

      • Perhaps you've forgotten that the US has used nuclear weapons in warfare (remember WWII?). Or that the US, as recently as the Gulf War, has deployed Depleted Uranium weapons (a simple google search will enlighten you).

        Stop thinking that the US is some holier than though state.

        Israel as well is no human rights champion. Just look at the atrocities that are going on in occupied Palestine.

        • Umm, hello? I never denied that the US used nuclear weapons in combat -- indeed, by doing so, we saved the lives of the hundreds of thousands of American and Japanese soldiers and millions of civilians who would have died in the invasion of the Japanese home islands (just read up on the invasion of Okinawa, which killed far more people than Hiroshima and Nagasaki, if you have any doubt).

          Are you suggesting that Mr. Hussein would use nuclear arms, would set such a high threshold on their use? After what he did to Iran or to the Kurds?

          Really?

          Your attack on Israel is equally misguided -- Israel has shown incredible restaint in its own defense, something which cannot be claimed about the murder-suicide bombers.

          So, holier than thou? Who knows. Holier than Mr. Hussein? Damn straight...

    While working at nasa, a co-worker told me this story once:
    Apparently in the 80's, he had been working on a satellite which contained a sensor to measure ground temperatures. The contractors who were working on the image processing for the data were so far behind, that the program would not be ready until a couple months after the satellite launch (a major PR disaster - no pretty pictures for the public to see!). So he was put on a crack team to hack something together that would be ready by launch time. What they ended up putting together was better than the specs. So the satellite launched and they got back the pictures and saw alot of interesting things... Like, gee, what's that underground hot spot in Nevada, and so on and so forth... So they were all pleased with themselves until the Feds came, classified their program and all the images, dumped all their equipment in a truck, and drove off.. I guess this shows why it is never better to do more than "government work" :)

    My father worked for the Defense Mapping Agency (the predecessor of NIMA) until 89 and he was surprised at some of the things that showed up in that book. Especially that the resolution of the KH-11 (best is 2.5 inches, so it can't read license plates) and KH-9 (9 inches) were in there.

    While much of the talk here is about either seeing celebrities naked baking under the Mediterranean sun or spying axis-of-evil governments and the such, the main use these images will have is that they are the first imagery of the Earth from space available. They do record images of the poles from where ice cover can be estimated. Again, forest cover can also be estimated from a time before civilian satellites were a reality. In other words, these images provide us remote sensing data from quite a long while ago. This should help the investigation of better climatic models and so on.

    As mentioned in another post, the USGS [usgs.gov] webpage itself is unusable unless you're running Netscape 4 (windows or linux only) or IE for Windows.

    I think it would be a good idea for as many people as possible to email [mailto]the maintainer of the web page.

    Unsurprising for the gov't to so thouroughly screw-up like this, especially with Interior Secretary Gale Norton [washingtonpost.com] at the helm. FWIW, she is facing contempt of court charges for lying in Federal court during a trial of gross mismanagement of the Native American Trust fund. Mismanagement by completely failing to secure a computer system...

    Hell, why don't we all email Gale [mailto] herself?!
    • Your link is messed up -- it should be a .gov [mailto].
    • I'm not going to defend Gail Norton, but FYI, the problems with Earth Explorer were created long before she was appointed. Where to start?

      You (we) elected several administrations who saw government-funded code as an Evil Thing that sucks the life-blood (money) from deserving private enterprises like Microsoft. There was a federal mandate to use COTS wherever possible.

      The responsible government PHBs, never a group to question an edict or make a decision based on facts, decided EE would use COTS. The government PHBs gave the decision to the private sector coders (contractors) to implement, based on a commercial product the government PHBs had chosen.

      Many months and man-hours later, the valiant coders had done their best to turn a mouse scrotum into a bowling-ball bag, but as you've noticed, it still has limitations.

      So, kids, the moral of the story is: Don't post about "my tax dollars at work", be thankful the government is committed to using COTS and protecting your jobs - even if the end product sucks.

    I used to live on RAF Woodbridge in the UK back in the 80s (go Warriors!) and was there during the infamous Rendlesham forest UFO sighting [google.com] (of Unsolved Mysteries and East at Left Gate fame). One of the better theories I've read about the whole thing was that the UFO story was a cover story for retrieving low flying spy satellite film canister [pipex.com], which, frankly, makes a hell of a lot more sense than the UFO nutters who are convinced we were doing all sorts of who knows what with ET.

    • Absolute bollocks.

      While there may indeed have been film recovery of satellite films (this sounds marginal, but not outside of the realm of possibility), the idea that the film was designed at an airbase if the parachute failed is absolute bollocks.

      given the aerodynamics of a tumbling film canister and high altitude winds or whathave you, they'd be lucky to hit a given county, much less a given airbase. The plan is stupid--if the film cannister is designed to potentially survive a parachute-less fall, why would they bother with the parachute?

      That there was something top-secret flying near an airbase during the cold war is not hard to believe. The notion that this was a film cannister recovery device with lights on it (let me get this straight--it has lights on it AND is designed to renter the atmosphere?) is incredibly hard to believe.

  • I doubt we'll see Chernobyl pics; they're too recent for one thing. But it would be fun. Anyone remember the early days of it when the US was reporting the event based, so they said, on spy sat pics, and non-communist central and northern Europe was reporting contamination in their air. But the line from the USSR was, "No, we don't have any problem. No we don't need your help. BTW, anyone know how to put out a graphite fire?"

    In the eastern block, news of the event was only reported about a week afterwards. A joke going around Hungary (which borders the Ukraine) was, Q: Why do we celebrate the October Revolution in November? A: Because that is when TASS felt fit to report it.

    I've read articles about the technology behind these -- it's pretty amazing. The pictures were not "beamed" back to earth -- they were taken on film and the film parachuted back.
  • Panoramic Imagery (Score:5, Informative)

    This is all great and all, but I have worked with corona imagery (after 1996) and it's REALLY hard to use.

    First of all, the imagery is not vertical, it's panoramic. Great for intel agencies, not so great for mapping. It's almost impossible to orthographically rectify, and hence use for anything useful. The resolution of the film is very good. It's something like 150 lp/mm, and the stereo is very good, but it's a pain in the butt to do panoramic stereo without special equipment.

    second, geo-referencing was accomplished in a brilliant, if arcane way. A second camera was involved that took pictures of the stars 180 away from the image. To find out what the picture is of, you need starcharts and a lot of math to figure out what stars you are looking at, where the satellite was, and what the picture is of. The equipment to do this in a useful environment is VERY expensive.

    third, it's panchromatic and not IR sensitive. You can see some ground features, but nothing environmental, and not all that much of historical significance. Consequently, the imagery has not been used for as much as had been hoped.

    Imagine - hanoi appears to be at the juncture of two rivers, and beijing seems to have some sort of big square.

    With intelligence-gather incapabilities like that, no wonder we won the cold war.

    They didn't use satellites to make those, but spyplanes.

    Geez, has no-one seen thirteen days?

    Wouldn't it be possible to fit them together like a jigsaw puzzle to find out which ones weren't declassified?
    • > Wouldn't it be possible to fit them together like a jigsaw puzzle to find out which ones weren't declassified?

      Knock yourself out. Meanwhile the rest of us will just read the article:

      > NIMA is releasing virtually all of its imagery from these programs except for imagery of Israel.

    • Since no one would bother shooting every inch of dirt, probably not. This WOULD be an amazingly interesting thing to do, though. You would have to write some pretty good software to do it, reconciling your images to a three-dimensional model of the earth, stitching, and so on; But it would be extremely interesting to see what it looked like.
  • I don't even want to IMAGINE what they are taking right now. With the way technology advances, I bet the latest satellites can tell you how many ants are running around an ant farm.

    And it's no wonder how they were able to missile-attack a *car* in Yemen from an un-manned aircraft! They can see everything now!

    Rumor... a friend told me this story a year ago, don't know if its true and didn't find anything about it after a quick search on the internet... but here goes:

    My friend said "

    I had a friend who used to work for the government... years ago he processed the photos that the US spy satellites took. One night at dinner the discussion had wandered onto the topic of the atomic bomb and its potential uses in a modern conflict, and someone says something to the effect:

    "... the US is the only country that has used the atomic bomb against another nation..."

    At which the friend spoke up, "Except for the time when the Russians bombed the Chinese."

    Everyone at the table stopped talking and looked at him. "What!"

    "Oh you guys didn't hear about that did you..."

    A rough outline of the scenario...

    Back in the late 50's or early 60's sometime the Russians and the Chinese are glaring at each other across the Siberian border of which some remote corner's exact boundries are in dispute. Each country lines up some number of troops and tensions are a little high. Finally the Russians move their withdraw their troops back about 10 miles... the next day the Chinese advance 10 miles. A few days later the Russians retreat 25 miles... over the next few days the Chinese advance 25 miles (meanwhile the US spy satellites are catching all of this in photos). A few more days go by and the Russians retreate 50 miles and the Chinese advance once again. So the Russian retreat 100 miles and drop a nuke right above the Chinese! ... From that point on Chinese ceased their dispute over the Siberian border.

    Is this true! How come no one has heard of this story? Supposedly the Russians weren't going to tell because they didn't want to attract international condemnation. Besides, they had used in their own territory. They could claim it to be a test.

    The Chinese? They didn't want to have to answer the question, "What was China doing with troops deep in Soviet Siberia."

    The US? Why were they silent? That is top secret, but maybe some of the declassified photos show the events...
  • Sorry.

    I meant, how long will it be, given some of the other things on slashdot today about the US Gov't taking things off public web sites, before someone decides to make all those protected too?

    After all, it would be Un American to make the information available without someone profiting on it.
