B 17 Crash

My background is having been a jet aircraft mechanic, (crew chief,) maintenance man, (Phantom Phixer) back in my Air Force days.
This year i took a flight in the B-25 Mitchell, when it was making the rounds here in Sacramento with the B-17, and B-24.
When were all the the fuselage of the B-25, before engine start up i asked the pilot, how many hours are on the airframe, and the engine(s).
On the airframe, must be many thousands, and thousands, for something that old.
An unknown amount of time.
As far as engines go, i never got an answer to that question of mine.
That B-25 on engine start up those engines, spit, sputter, back fire, sounding like large fireworks, going off, all the way down the taxi way, to the end of the runway.

Sounds like that B-17 crash had problems with an engine, maybe two, of them, and just didn't have enough power, lift, to gain any altitude.
Guess the NTSB will have it figured out, given time for the investigation.
After all, there were a few survivors of the crash.
