When I was stationed in Cali it was at Moffett field which now Nasa owns (aimes) , there are two old blimp hangers there one we had the other they kind of used to mothball stuff. It was always open guess the door was messed up, pretty cool stuff inside the old X wing, ton of different prototypes etc. The housing I lived in literaly behind us was one of the bigger wind tunnels, pretty cool to see that puppy in operation. When it started up you thought the rumble was a earthquake.
