not surprised there, because I already know that you should never be behind a jet engine while it's running, it can kill you. You're looking at at least 40,000 POUNDs of thrust shooting out of that engine.
WOW, dang!!! I was expecting some swerving, but that totally beat my expectations!
BTW, for any film-score buffs around here, is that background music from Lord of the Rings? It sounds an awful lot like the Mordor theme. (Yes, I am a big geek.)
