I Just got back from a trip up North to visig my daughter and family. On my way home, I decided to visit the National Air and Space Museum at Dulles airport, and I'm very glad I did. I just wish I were younger, because I wore myself out in the four hours I was there. I spent about a half hour looking down at the simulator and vintage aircraft section, then went to the tour desk on the lower level to join a 2 hour guided tour, which I highly recommend. After the tour, I spent a while retracing my steps, especially in the Space hangar, where I revisited the shuttle Discovery. Then I went to the commercial aviation section to take a closer look at the prototype Boeing 707, which I had seen flying around Seattle on test flights in 1955, when I was in the Army. I took well over 50 pictures of the various aircraft and space vehicles while there. I had to quit early vecause my legs were failing me agter 4 hours of trudging around and I was exhausted. One could easily spend two days at this marvelous museum and probably not see all the exhibits. For those of you planning to visit the Washington area, budget a day or two to visit the museum, which is located on Va. route 28, south of the Dulles airport. You won't regret it. Admission is free, but you have to pay a $15.00 parking fee.
