Thanks for the advice. I am very, very thankful my son is fine. I'm sure much worse injuries are possible.

I agree with you that going after the passenger is just not going to work. The biggest problem is identifying her to begin with.

I realized that I should have stopped her when I was talking to the cops, and the officer said "Well, it probably wouldn't have done any good, since it's just an accident." For crying out loud, is this his attitude at car accidents, too? "Well, he didn't crash into you ON PURPOSE, so tough luck. Buy yourself a new car."

Why are there cops in airports anyway? I have yet to see them serve any purpose whatsoever. All they do is watch law-abiding citizens get hassled at the security checkpoint, and when they have a chance to actually do something, they throw up their hands and say "Oh well, too bad so sad".

Anyway, there is also the issue that it wasn't her bag that was heavy. It belonged to a passenger in the bulkhead seat. He waited to see if my son was going to be OK, and he apologized that it was his bag that hit him in the head. I quickly said thanks for the gesture and headed out the door to go downstairs to the waiting ambulance.

Besides, what if I look at it this way -- it's Delta's airplane and Delta had every right to prohibit large, heavy carry-ons in the overhead bin. They have a closet on the plane, conveniently located near the coach bulkhead seats (we deplaned using door 2L). Shouldn't the closet be used for bulkhead passengers' dense carry-ons that would normally go under the seat in front of you?
