I just saw a reasonably interesting movie on youtube called "Battle Taxi" about Rescue helicopters in the Korean War. Lots of flying, some pretty impressive. Main actors were the H-19 helicopter (I remember assembling one when I was a kid) with guest appearance of H-5, which I liked to draw. Additional guess appearances in action, were, F-51s, F-80s, F-86s, f-84s, B-29s, A-26, and Dumbo the amphibian. Standard mix up of various aircraft, but overall fun to watch if you like Korean War stuff or helicopters. Oh, and a special guest appearance 22 minutes into the show, was a helicopter flying over some Army troops, and there it was, a Skysweeper with antenna rotating! I had to take a double look at that. While it was in service in '51, I'm sure it was never in Korea. I remember putting that model together, too. One other lesson that was apparent here, arm rescue helicopters or provide armed helicopter support!
