I don't think that the MOAB killed anyone.

Gaining applied force over that distance is exactly what you just described...so?  Agree to agree?  

Kinda sorta. The over pressure is the highest when the two waves first meet which is at some point out from but very close to ground zero. Jehanne is right though in that it loses energy the further from that point you get. That being said the over pressure that results from an air burst is still higher than it would be in a ground burst because there is no reflected wave adding to the effect.
