Technically you are right, but I was trying to keep the explaination at a level that non-aero-heads would understand. :)
Really, though, I'm not that familiar with jet engines. Reciprocating and rotaries I think I understand but not jets. What's the advantage to moving air through the engine faster - does one get higher thrust out of it? How does one start one of these - wouldn't the air have to already be moving through the engine at that speed before turning it on?
