wow, I thought I was crazy. I was in me college dorm with the windows closed and it still sounded really loud. as for the trails i dont think its possible, but I would not doubt somebody on those helicopters was being stupid. as realist states, "Soldiers are, at best, misguided sociopaths willing to kill for college money." and if it was " ...just some joker pilots exploiting your self-important paranoia for a little fun." I wasnt laughing.
