When I was a kid, my orthodontist owned a helicopter. When you got your braces off, your reward was he would take you up in the helicopter. He and my dad became friends and my dad got to go on a helicopter ride with him. A week to the day after my dad's flight, my orthodontist was flying another friend and they crashed into a Cessna mid-air. I was due to get my braces off 3 months later.
I still haven't been in a helicopter.
