Okay, so the icing story isn;t holding up. How about turbulance? Would you believe turbulance brought down 3407?
Trouble on the flight began when the plane's flaps went down at 2,300 feet, said Steven Chealander, a member of the National Transportation and Safety Board, at a news conference Saturday. The plane pitched forward and rolled in the air, but did not turn over. The turbulence unfolded so quickly that passengers on board would likely have had little time to realize the aircraft was crashing, he said; pilots didn't have time to send a mayday call.
Although witnesses reported seeing the plane nose-dive, Chealander said that investigators had found the plane's cockpit, tail, engine and wings positioned "as they should be if laying flat, not if it was nose-down."
"All we know is that the airplane hit flat," he said. "It was a sudden catastrophic event that took place, and then 30 seconds later it impacted."
... except that now there is an eyewitness to the actual crash who saw it go in nose first.
