Let's face it, BV is a professional, what he lacks in tactfulness dealing with people, he makes up for in his strive to produce a product that he will support and that has been proven to work. I can imagine his frustration with a huge number of "foamies" in the air and him trying to fly his very fast, very expensive, demo planes. I saw them fly at TG and was impresed that he was getting this type of power and performance from them, I would have thought the electron crowd would have been beside themselves with the technology e was bringing to the table. I can aso sympathize with him if he was trying to fly, avoid all the park flyers, and being yelled at by a flight boss. It would aggravate the best of us, and he was a fighter pilot, and he is as good on the sticks as anyone.
After reading what the people who witnessed this had to say I can imagine that both parties are to blame. Too bad they pissed him off though, it would have been good to keep him on their side. His voice does speak volumes. It may not hurt them in the short term, but like the sign says...
"Lord grant me the serenty to accept the things I cannot change, the courage to change the things I cannot accept, and the wisdom to hide the bodies of those people that I had to kill today because they pissed me off and also, help me to be careful of the toes I step on today, as they may be connected to the butt I have to kiss tomorrow".
