hi:
as for the tail gunner seat, you would not go deaf. once the plane is in the air, the noise is very little, yes on take off it will rattle your head, but not in the air. i know this from my skydiving days and sitting in a DC3 (c-47), it was very loud on the ground and take off, but once over ,say 100ft, it got quiet. i dont mean you could hear a pin drop, but you could talk to the person next to you no problem.
