if ya do the math, a ping of 100 to the HTC servers from two players can give you this senario.....
plane flying at 300 is about 440 feet a sec, one tenth of a second ( ping 100) 44 feet , two planes with same ping, 88 feet differance
you see both planes coliding, the other guy will see two planes 80 feet apart, giving him time to manuver.
