I am surrounded by airplane enthusiasts. My brother is a pilot and if my husband wasn't a chemistry professor, I suspect he would find his professional way into a cockpit as well. Although it isn't the National Air and Space Museum (which I have spent numerous hours in despite the fact that I prefer the Museum of American History) Utah's own Hill Air Force Base Museum is pretty awesome. Brian says it has an "outstanding collection of airplanes--a surprisingly good one for Utah."
Anytime we are traveling north on I-15 Brian tries to get us to stop for a "quick" tour. Of course, Travis and Abby have caught the aeronautical bug so they listen intently to all of Brian's explanations.
I caught snippets of "roll, yaw, and pitch" in this lesson. As for me. . . well. . . I enjoyed the photographic opportunities.
Hill Aerospace Museum is free (which always appeals) and not only are there planes outside, but there are several hangars to explore inside as well.
In September many of the planes are open to the public. Last year (after a soccer game) Brian and Abby were able to go inside the cockpit of a B-29. In Brian's words, to see the original wood and electronics from a World War II aircraft was "pretty cool."
