It seems impossible that the aircraft could be upside down when it hit considering that it had just lifted off, so perhaps a rotor tip caught the water on the way in and that then flipped the aircraft over into the water?


I don't know anything about that crash (or helicopters), but according to the info below, I'm wondering if the rotors stop for some reason, the helicopter would FALL upside down?

From The Space Review [quote][/quote]

"Because the heaviest part of a helicopter is the engines mounted over the cabin, most helicopters immediately tip over when they hit the water and crews are trained to exit a sinking upside down helicopter."

Also (same source): "And one of the dangerous aspects about helicopters is that bad goes to worse very quickly."
