sorry for lumping you in with Dan, but you were the one who had to make the completely irrelevant jab in this thread
As to an engine failure....wasn't one of the explanations for the USAF CV-22 crash in Afghanistan a dual engine failure?
It was a suspected single engine power degradation, which was categorically ruled out by the air force as the only suggestions for that conclusion was from prop rotor divot spacing in loose sand and IR video feeds from an A10 at 10,000'.
The air force concluded that was hardly conclusive evidence in the face of the way-too-hot approach profile taken by the first chalk, in addition to absolutely no supporting evidence from the pax testimony and crew during descent.
Did the MH60 suffer an engine failure to bring it down? I havent read a single story detailing what happened exactly.
