Okay, after watching that video, I take back anything I thought about unreliable eyewitness testimony about a flipping-over aircraft.
From the distance people saw it, and given the lack of a tail surface to indicate "right side up", it sure looked like a roll-over. Simply a miracle it didn't do the Sioux City UA232 roll-and-explode.
Let's don't be so quick to toss out data even though people do sometimes get it wrong...
