When I was about 3 years old my dad flew small airplanes. One day the Flying club got a new plane and it looked like it had pontoons on the landing gear for water landings, so I asked my dad "Can this plane land on water?" my dad responded "Every plane can make one water landing." I was only three years old at the time so I didn't dwell on it too much until I was about 16 that phrase just came up in my head and it clicked. It was a real hurr durr moment.
