This is a short (only 7-1/2 minutes) documentary about the restoration and first flight of a B-29 named "Doc." With Doc's return to flying status -- that means there are now just TWO B-29's in the entire world that can get airborne. The other flyable B-29 is named "FIFI.” FIFI performs "legacy flights" at the annual EAA AirVenture fly-in at Oshkosh, and maybe Doc will be flying there sometime soon, too.
