Yep. There was a feature not too long ago on History channel I believe where they found the crash side and tried to reconstruct what happened. I think some papers are by now released by the Pentagon... (Mods, feel free to remove if too far off topic).
To topic - wasn't the FedEx that made it barely down (was it BOS) where the hazmat was not prepared properly by the shipping company or even factory? So that seems to show that on the side of the freight its tough to change things as too many involved but that a system on board is really neccessary.
