The Frontiers of Flight Museum at Dallas Love Field is like many such museums: displays and aircraft hanging from the ceiling or lined up on the floor. This museum actually doesn't have that many aircraft, and has none from WWI and WWII (only models).
However, it has one piece of history that is remarkable - the radio operator's chair from the Hindenburg! Yes, it seems that the radio room was heavily insulated in order to prevent sparks from the radio from igniting the hydrogen used to float the blimp (smart move). As it turns out, the same insulation saved the radio room during the inferno, which for all that it burned at up to 4,000F, burned through very quickly.
Somehow, the radio operator's chair - a metal frame with leather seat and back - ended up here in Dallas, Texas!!! It is not showcased, but is just something I stumbled across many years ago (although the museum has moved, the chair is still part of the exhibit).
Oh, yeah, there's other stuff like the Apollo 7 capsule (on loan from the Smithsonian), the "flying pancake" (the prototype of an unusual looking plane), and a 737 whose nose is inside the hanger while the rest is outside, looking like it crashed into the building ;-).
It's not the biggest collection of stuff, but is interesting especially for those wanting to learn about aviation (i.e., children)...and blimp enthusiasts ;-)
If you love aviation, or you just have a long layover at Love Field, this is an interesting place to spend a few hours. The displays are very comprehensive; they cover the beginning of flight with a scale model of Da vinci's drawing of a flying machine, hot air balooning, military aircraft from WW I, WW II, and shoppers used in the Vietnam War, and space exploration. It is mostly manned by volunteers who are retired pilots, commercial and military.
There are shops for snacks as well as souvenirs. There is a modest admission charge.
Situated at Love Field, the frontiers of flight has numerous historic aircraft and simulators. It also has some modern southwest mock ups. A nice place to spend a few hours.
