Was stealth camping in Northern Virginia last weekend.

Trip included a visit to the
Steven F. Udvar-Hazy Center next to Dulles Airport. It's a companion to the Smithsonian Air and Space Museum that's in D.C. along side the Mall.
Beside exhibits like an actual SR-71 Blackbird.

The Space Shuttle Discovery

And planes of every type



Is the alien mothership model used in the movie
Close Encounters of the Third Kind
If you look closely at the model you might be able to spot Darth Vader's space ship (the original Stars Wars had come out earlier in the same year as Close Encounters)

R2D2

WWII fighters. Probably from the famous
Lost Flight 19.

A VW Van

And a alien graveyard. Reference to Area 51 perhaps?

Will have to watch the movie again to see if I can spot any of these.
