Finally got the time to watch it. It's always interesting seeing sophisticated design work that was done in 2D with paper and pencil (no 3D CAD back then). Interesting seeing all the assembly techniques. I get a kick out of those hand-crank starters on radial engines. Thanks for posting.
OK, you got me on a P-47 jag. Here's a video of the P-47 in action that YouTube offered me:
I just thought it was interesting that the P-47 was officially designated Thunderbolt and unofficially called "The Jug". And that the A-10 was officially designated Thunderbolt II and unofficially called "The Warthog". Both tough, ground support aircraft.
