I couldn't agree more with Prowler, this kind of response to someone out having some fun just makes my blood boil. The pursuit of "safety" is the quickest way to never experience anything in life, which begs the question... what's the point in living then exactly?
I'd heard about this incident but had never seen video of it. The 'outcry' from an aviation illiterate public that fears their own shadows these days aside, I thought it was a masterful bit of flying, well done.
I know Riggs, met him last August, sat in his jet and flew formation with him in another L-39, months before this occurred. At no time did he do anything that I would consider crazy, a very competent pilot. As for the FAA being worried about the mechanical state of his L-39, that's hogwash. That thing is immaculate. It gets worked hard and well taken care of. It was perfectly maintained by its previous owner as well, whom I also know (and who helped me immensely during development).
This incident reminds me of a drive I took in my mom's porsche as a teenager, reaching speeds well over 100 mph in the pre-dawn hours on a deserted road. The next week she got a letter from the police advising that her car was seen "moving at an unsafe velocity" on that particular date. That letter is still taped to my fridge 15 years later. I consider it trophy. "On this date at 4am your son was *living*".
