Grimmrad: "Can someone she light on this - would it take one of these vehicles to presumably cause this if it shifts position and therefore COG, two, more? Chain reaction where one hits the next which rips loose etc?"
Reportedly, there were five MRADs on the aircraft. An MRAD weighs ~25,000#. Even in a 747, this would be a considerable load shift depending on the loaded location and the distance moved.
This occurred on a military base, so the Afghans are out of the investigative picture, I'm told. Let the NTSB review the evidence and announce the cause.
