A historic C-47 twin-engine prop plane crashed at the Burnet Municipal Airport in Texas on Saturday; all 13 passengers onboard survived.
Video looks like left wing stall. Perhaps C47 took off before sufficient airspeed. (or sudden loss of power an left engine? )
Probably the former since one would expect the tail to be raised to gather speed before easing her off the runway.
That didn't happen, tail was still in contact with the deck at point of take off!
Third possibility that C47 was loaded tail heavy would point to pilot error in not aborting take off when he found tail
could not be lifted by moderate forward stick pressure.
Two videos go to second one, which was captured by smart phone, to judge for yourself what went wrong.
