So strap yourselves in for seven things you didn't know about Armageddon. Thanks to the favorable light it casts on the space program, the production of Armageddon was granted unprecedented access to many of NASA's facilities and equipment. Like this vacuum chamber that can fit a space shuttle inside, and has a 40-ton door. This hangar, which is so tall they had to constantly run the AC so clouds don't form in the ceiling. And the neutral buoyancy pool for simulating zero g in astronaut training, which is 40 feet deep, and holds 6 million gallons of water. Bruce Willis and Ben Affleck were actually the first people to go inside it who weren't affiliated with the space program. But with all this access, Michael Bay declined to shoot at the real mission control, (Sound) citing that it just Wasn't sexy enough. Instead, they slapped a NASA sign on the front of an herbal supplement company for the exterior, and the rest was shot in a studio. And that's pretty much Bay's mantra right there,
