Abandoned & Little Used Airfields 329

Back on topic. The one group that does know of the existance of all of these small little airfields is the DEA. With a small prop engine plane able to land nearly anywhere that's fairly long and flat it makes it virtually impossible to make any attempt to stop these planes from landing and dropping their loot.
With the infrared technology (nightvision) and other GPS devices these planes can fly in the dead of night during a new moon phase with no lights on and still relatively safely land and takeoff. So yes, these are not forgotten air strips, but there are some that wished they were.
Even more unrelated, where the hell do you get gas. Seeing as I've never flown a plane and definantelly not the lawnmower with wings kind. How does one go about getting gas? Do you just really fill up the tank, or in a pinch can you throw some standard disel in there? Always bugged me because I've never seen a plane gas station before, seen them for cars and boats, just never planes.

Anyhow, there are various grades of aviation fuel, everything from kerosine and derivatives that the jets burn to 110 octane Low Lead, 100 octane, and avgas (essentially what you put in your car). The fuels are injected with color-coded dyes do you can check to see if you've got the right gas in your plane. 110LL (the most comon variety for small prop planes) is blue. If you mix another fuel type in with it, the dyes are designed to combine chemically, and the fuel becomes clear.
As much as I'd love to own my own airstrip (I've been a licensed pilot longer than I've been licensed to drive a car), it's a regulatory nightmare to get one operating. Even as just a private strip, you've got everything from zoning commisions to public noise ordinances to deal with (in the U.S. anyhow).

Sorry, but you are referring to 100LL (100 octane low-lead). There is no 110 octane. There is 80 and 100LL. 80 is green and 100LL is blue. 100LL is by far the most common, 80 is rather hard to find.
There are places that have "self serve" pumps where you pull the plane up to a pump. But most places deliver it by truck and have an employee pump it.
Avgas 80/87 octane is RED, 100/130 leaded is GREEN (Score:3, Informative)
100LL (blue color) is a misnomer, because it's lead level is not very "low" at all. It has up to 2 grams per gallon of tetraethyl lead. 80/87 only has a max of 0.5 grams pre gallon of TEL. 80/87 leaded "regular" avgas has almost disappeared from the market, forcing many pilots who need the lower octane, truly low lead fuel to have to buy unleaded auto fuel and mix it in about a 3:1 ratio with 100LL. With so many auto gasoline suppliers now contaminating their gas with ethanol (which means a significant amount of water getting in the gas too due to hygroscopic nature of ethanol), pilots cannot use auto fuel in many parts of the country because at altitude, the temperature drops and the ethanol/water will freeze in the fuel lines resulting in engine stoppage.... not good.
Hopefully soon, the new 82 octane unleaded avgas (colored light purple) will be put into production and available thru distribution channels soon.
There also are programs to develop a pure ethanol aviation fuel (E-85) but that requires both the aircraft and engines to be specifically engineered to keep the fuel systems sealed from the atmosphere (to keep water vapor out), keep fuel system pressurized with dry nitrogen, and possibly also keep it heated too. Of course ethanol has much lower calories of useful energy in it per mass, so useful load and range of these aircraft are greatly reduced.

Way back when I was learning how to fly, I pumped gas for a small FBO. They let me fly at cost, paid me a bit, and let me experience the glory of blue-juice engineering. Some n00b did just that - ran low on gas and ditched in a little used field because he did not do his math first. He called, I drove a fuel truck for a few hours and filled him up. As a side note, most of those little airports are marked on maps and a good GPS will have them as well. Well worth the cash to have a little box that will always give you a pointer to the nearest field when you have errata in the air.
Usually, the smaller non-turbine stuff will use 100LL, which is pretty close to normal high-octane gas. One might put in normal gasoline in a dire emergency, but running out of fuel and being stranded at an airport is not such a beastie. I suspect it would give you the same problems a Porsche running 95 octane unleaded - with a stalled engine being a serious matter on takeoff. I have a 1958 Stitts playboy with a Continental o200 engine. I could have set it up for normal gasoline, but 100LL is pretty easy to come by.
For the jets and other turbine-powered stuff, they use Jet A, which is essentially kerosene.

But really, all a small Cessna needs to take off or land is about 1/2 mile of relatively flat terrain. If conditions were right an experienced pilot could land on a well-mowed field or dirt road. But most established airports with attended hangars & other services are listed on charts e.g. the ones from Jeppesen [jeppesen.com].
And the reason nobody ever sees aviation fuel pumps is because you're never at little airports like this. Even small planes fly much faster than cars can travel, so they're not always closely spaced, but believe me, they're everywhere. Probably at least one to a county (in the midwest.)

Now that The base has been officially closed, friends from the area said that those plans have been scrapped, and both hangars will be destroyed.
This is truly a shame, since these hangars have such history in them. Also, they are tremendously usefull for the current airship industry.

Claim: The American interstate highway system was designed to be used for emergency airstrips in case of war.
Status: False.
Origins: Numerous folks swear Interstate highways in the United States must be designed so that one mile in every five is perfectly straight and flat. According to this whispered bit of facetious lore, if the U.S. ever comes under attack, those straight, flat stretches will be used as landing strips.
Richard Weingroff, information liaison specialist for the Federal Highway Administration's Office of Infrastructure and the FHA's unofficial historian, says the closest any of this came to touching base with reality was in 1944, when Congress briefly considered the possibility of including funding for emergency landing strips in the Federal Highway-Aid Act (the law that authorized designation of a "National System of Interstate Highways"). At no point was the idea kited of using highways or other roads to land planes on; the proposed landing strips would have been built alongside major highways, with the highways serving to handle ground transportation access to and from these strips. The proposal was quickly dropped, and no more was ever heard of it. (A few countries do use some of their roads as military air strips, however.)
Some references to the one-mile-in-five assertion claim it's part of the Federal-Aid Highway Act of 1956. This piece of legislation committed the federal government to build what became the 42,800-mile Eisenhower Interstate Highway System, which makes it the logical item to cite concerning regulations about how the interstate highway system was to be laid out. The act did not, however, contain any "one-in-five" requirement, nor did it even suggest the use of stretches of the interstate system as emergency landing strips. The one-out-of-five rule was not part of any later legislation either.
