I worked as a CFI and commercial pilot (small piston twins) for a while. I built my own ultralight airplane in my garage. I eventually also owned and flew certified aerobatic aircraft Pitts S2B, Extra 200, and Extra 300.
2 engine failures in the ultralight, one on takeoff below 100 ft, successful landings in both cases.
Brake failure on landing in the certified Pitts S2B, that was scary but uneventful.
Aviation is dangerous, but there is NOTHING on earth that can match it for the thrills.
