I really don't have a big problem with the ego, if you are successful in your profession and have extra cash to flaunt you should be free to flaunt it.
Sport Pilot,
This is a big part of the problem. I fly jets because I like to fly jets not because I want to flaunt ANYTHING. I don't expect ANYONE to sit down and watch me while I fly. Fact is that most of the time at non jet events that I and others fly at we are asked to fly by ourselves as demonstration flights. A lot of the time when we crank up our engines pilots that ARE flying land so they can watch. Not everyone can afford a jet nor does everyone that can afford one want one. They great thing about my local club is that their is such a diversity there that we all get along and fly what we enjoy flying.
