Good point!
Grizzled,
Damn good question! I too am no expert on this but I do not think that you have to be nearby to feel the earth move. My guess is it is 1> .Tends to confirm the BEA assumption that it was pretty much in level flight when it hit.
I think that is, if anything, more upsetting (no pun intended) , to think that a few more feet and it might have been so different...
