More of the Boeing Aviation Hanger
This is another view of the awesome Boeing Aviation Hanger at the Udvar-Hazy Center, part of the National Air and Space Museum. Without getting too specific, it's home of the Boeing B-29 Superfortress (Enola Gay), the prototype 707 (America's first jet airliner), a Boeing 307 Stratoliner Clipper Flying Cloud (the first airliner with a pressurized cabin) and a Concorde supersonic airliner.
The sheer size and quality of the exhibit impresses everyone, whether you're a plane nut or not (there's a pun in there somewhere). If you ever fly through Dulles International Airport, take a half-day layover and take in the sights. You'll be glad you did.
