bast0n,
So we are agreed it is the most likely cause. But are you sure, with no doubt whatsoever, that it was the cause?
For me, there is enough doubt. The thing I'm most curious about at the moment is how and why they got that close. If they weren't actually intending to do something there, it seems incredulous, rather than negligent that they should have entered the cloud/fog/mist that they must have before impact.
