I had a free morning on a trip to Dallas, and found the Frontiers of Flight Museum a great way to spend a couple of hours. The Museum has plenty of volunteer docents to answer questions about the exhibits. As a big fan of the Apollo maned space-flight era, I was thrilled with the exhibit centered around the Apollo 7 Command Module. Authentic Apollo space suits rounded out the Apollo exhibit. There was a significant Vietnam-ear display consisting of beautifully restored A-7 and A-8. The "flying pancake" was an experimental "flying-wing" type of aircraft was an interesting novelty. The T-38 suspended from the ceiling rounded out the Apollo exhibit, since the astronauts flew their T-38s frequently between Houston and the Kennedy Space Center.
