the bodies weren't wearing life vests. can you read anything into that? >> not really. you could say the plane fell suddenly which obviously it did if the wreg age is not that far from the last contact. so that means there wasn't any time to get people ready for splash down. and i think the fact that the wreckage on the surface is not too far from where the last contact is means the plane fell fairly suddenly. there's been a lot of talk about stall. stall is an aerodynamic. it doesn't mean the engine quit. it means the plane loses air lift. it looks like a stall because the wreckage is so close the surface wreckage to the last contact. on the other hand, the question is stall is typical. after something goes wrong. what is it that went wrong that caused the stall in that's the secret of the black box should help solve.
