A test of a foam fire-retardant at a hangar at South Dakota's Ellsworth AFB was supposed to run for 15 seconds, but something went wrong and it ran and ran, until more than a storey of foam filled the hangar, spilling out onto the runway and environs. The photos of this are stupendous -- imagine an airplane hangar filled to the top with shaving cream. Even better are the looks of confused hilarity on the faces of the air force personnel in the shots.Lots more great pictures at this [a href="http://cellar.org/showthread.php?%20s=b5a22752534694c7efa8f42f6db979f5&t=10491"]link.[/a]
