This is a true story, it happened near where I live when I was about two years old. There were two pilots flying a plane. Witnesses saw the plane go down. When the rescue teams arrived, they discovered: both pilots naked and one of the seats was tilted 180 degrees (flat). Neither of them were wearing seat belts. They were naked on purpose. (can anyone guess what they were doing?)
They were having sex, but nobody was controlling the plane. The right wing failed. They crashed.
