True story: Late 1970's, I get an extra ticket to see the NY Jets play at Shea Stadium. My very first live pro football game. It was a cold day in December.
There was an organized group whose hobby was radio controlled planes (and other flying contraptions). They did an annual show at Shea stadium where at half time they demonstrated their skill by flying around various planes and other devices in the stadium at half time. I was upstairs in the mezzanine (with the upper deck over my head).
It was either a flying lawnmower, or a flying dog house with snoopy on top that was flying around, pretty high over the stadium. Looked to me to be struggling, so I looked up and felt okay since there was a roof over my head.
Short story, the contraption fell out of the sky from up high and hit a fan in one of the field level seats near the field. He died, and that was the end of flying contraptions at Shea stadium.
