This is a very nice colour early 1950s period piece about the developement of helicopters. Watch for the Hiller Hornet prototype, Kaman HOK-1, Piasecki H-21 “Flying Banana”, Bell 47G, etc. Also check out the Continental DC-6 take-off, Capital DC-4s, plus GREAT COLOUR footage of the McDonnell F2H “Banshee” jet fighter.
