Smithsonian Unveils New Air and Space Annex (washingtonpost.com)

"... The new building is part of the National Air and Space Museum annex near Dulles International Airport that will give the public a close-up view of more than 200 historic aircraft -- from sleek spy planes to World War I biplanes.

This morning officials from the Smithsonian and Hensel Phelps Construction Co. gave reporters a tour of the main facility at Air and Space's Dulles annex, a cavern 10 stories high and covering the equivalent of three football fields...

....The new facility will house the Boeing B-29 "Enola Gay," the space shuttle "Enterprise," a rare Boeing 307 Stratoliner (the first pressurized commercial airplanes) and the Dash Eighty, the prototype for the 707 jetliner. Other artifacts will include the Boeing B-17D "Swoose," the oldest B-17 Flying Fortress in existance from World War II. ..."

The Swoose was the flagship for my grandfather, Lt. Gen. George H Brett. That means it was the airplane that he used to fly from there here. The pilot was Maj Frank Kurtz who later named his daugther Swoosie.... and she became a movie & tv star.
