Sparky,
It is amazing to me the patience you have! I spent my career as a professional pilot, test pilot and FAA pilot examiner, so you can imagine how many "know it all's" I've seen. It has never failed that the smartest guy/gal in the room was the one who just listened and kept quiet. It never, ever failed to be the case! My thoughts have always proven to be true, "no matter how smart you think you are, there's always someone in the room smarter than you." I've had trainees who were military test pilots, Blue Angels, Thunderbirds, professional aerobatic pilots, etc, etc. Unless they were asked about their experience, they just quietly observed and absorbed the information. Every time!
Thank you Sparky! Well done!
Paul
