While digging around for obscure German WWII aircraft (it's a slow day), I found this nifty collection of photographs of the old Smithsonian Paul Garber Storage Facility. This was where most of the Smithsonian's air and space collection was held, and it was, well, sort of open to the public. You had to make an appointment, and tours were given most days.
I saw it back in 1995, four years before these were taken, but still recognize most of the things in the pictures. It's closed now, and I never got around to going back. Ellen claims to be quite disappointed, but she tends to roll her eyes when she says it so I'm not sure I believe her. A dusty, un-airconditioned collection of warehouses full of junked old airplanes... what's not to love?
A lot of these aircraft are now on display, but many are not. I hope once they get the restoration section of the annex built that The Swoose (the only "shark-fin" B-17 in existence) and the Go-229 flying wing (a Nazi "might-have-been" that never flew) are at the top of their "to-do" list.
