That thing with sitting in the tower still being shot has happened to me too. I don't think it's anything to do with the Internet, but rather the number of packets saying "You were shot by this/these guns" just keep on "landing" hits on you. For example, if x___x lands 15 rounds on you, but the first 2 kill the pilot, I think that the other 13 rounds are recieved by your computer, to ensure that you hear each and every hit that x___x landed on your plane.
That's just what I think.
