It was not uncommon for one C-123 to "jump start" a second 123 that had Starter problems on a Piston Engine by providing sufficient prop wash to windmill the recalcitrant engine to do the equivalent of an In-Flight wind milling start up.
Short field takeoffs at times would result in liftoffs and initial climb below Vmc airspeed.
I spent many an hour flying helicopters with a former Air America Pilot who flew both helicopters and airplanes for that "Airline".....including the 123.
