Oh, OK there Chuck Yeager...When is the magic number to be a pro like yourself? By the way, I didn't get to the Airlines after 400 hours. I have 600, military experience as a crew chief on a DC9(I preflighted, postflighted, set up the APU and avionics for flight, inspected and serviced the sircraft; also I have worked the FBO route(fueling, towing, washing, etc, etc.), I have also loaded UPS 757's with cargo for a while). I may not be a "Top Gun" yet, but I am descently knowledgable around aircraft. And my 600 hours were hard earned my friend, even if I did not go all the way through 1000 hours of instructing. I still feel like I have learned alot. I successfully trained seven individuals for their PPL checkrides, and each one passed the first time.

Point is, you don't know everything either. And, there are many low-timers out there who do have a vast array of other aviation related experience...
