From what I hear on local news - local stations embedded guys with the 82d -- the crew chiefs dump the stuff out away from the people because if they land and try to unload the chopper gets mobbed by people wanting to get away from where they are. By mobbed, I mean like 50+ people in the back of a BlackHawk, not a real safe situation. So the chopper crews spot an encampment, dump the stuff out a ways as fast as they can, then beat feet.

Once they get vehicles in they will start to truck it in to the camps and attempt an orderly unload.

Something beats nothing anyhow.
