That's really impressive.

Bad title considering that (as the article states in the first paragraph) Trieste made it to the bottom of the deepest part of the ocean (Challenger Deep in Mariana Trench) in 1960 with a crew of two. I'd say they have the record and since you can't go deeper...not sure it can be broken unless the ocean changes depth there.

If you're in the DC area the Washington Navy Yard museum (open to the public) has Trieste hanging in the back (right next to Alvin -> http://en.wikipedia.org/wiki/DSV_Alvin which was used to explore the Titanic). It's worth the trip if you're local or you've been to DC enough that you're not interested in going to the Air and Space museum again.

TFA: "Borosilicate glass, also known as soda-lime glass..." That's like saying "Bronze, also known as brass..." The two are compositionally quite different.
Pyrex (R) is Corning's trademark for the borosilicate type and it is commonly used for laboratory ware, oven windows and such. It was also used for the big 200 inch (a bit under 5 meters) mirror at Mt Palomar. [wired.com]
Soda lime glass is the more common type used for windows and beer bottles. You can quickly tell the two apart by looking edge-on into the piece, soda lime glass has a greenish cast.

Also the article says that borosilicate is another name for soda-lime glass, which it isn't. Borosilicate is the good, strong, high temperature glass. Soda lime is the cheap, easy melting bulk glass.
