I mean this in the kindest way possible, but you need to learn the gift of humility.  Almost 10 years ago when I was your age, I felt quite the same.  You're going to learn that no matter how much you know, it is almost certain that there is someone who knows more than you.  You may know a lot about aviation or flying, but there are certainly people who have been flying for decades who could bury you alive with their knowledge. This isn't to take away from your offer for beta testing, but is passing on a lesson learned.  My big wake up call came when I started medical school.  I thought I knew a lot and was going through basically a formality in getting the degree.  Now that I have nearly graduated I realize that I would have killed many dozens if not hundreds of people if I walked out with the knowledge that I had just three years ago.

ESzczesniak, I have to disagree with you.  I think in this case, some bragging is in order.
aal763 is trying to sell himself and show Captain Sim that he is qualified and would be an asset on the beta team for the 767-300 being developed.
It is a little difficult to sell yourself and be humble at the same time.
I own a sign company and have been a sign maker for almost thirty years.  When I say "I'm good" it isn't bragging, it's just fact.

aal763 isn't claiming to know all there is to know.  He is saying that he knows enough to be an effective beta tester, and I believe him.
