Has the eyewitness account translated in post #202 been authoritatively discounted? The claim is that the aircraft was throwing up sand from off the left hand side of the runway and that the right wing then struck the ground, with the aircraft then disappearing off to the right.
This would seem to be consistent with an initial swing to the left on losing power from the port engine followed by an attempt at recovery that was hindered by impaired directional control.
If, as has been reported more recently, the aircraft became airborne, impaired yaw control may have indicated that an attempt to land on the remaining runway was the least worst option.
Perhaps those guys were just a few metres sideways from success.
