FWIW, having read almost every thread posted in the jets forum over the past 6 years, Kevin's response above is about the best answer that has ever been posted on this topic, and in my opinion, beyond the obvious (which Birdofpray chimed in with [although there are some that would disagree] regarding static and dynamic thrust) Kevin's response provides enough detail that I would point people to this thread in future discussions of this.

Well done!
