When I was 8 years old, my family took a camping trip. We had a disaster and forgot our big tent, so we had to use a much smaller one and cram 5 people in to sleep for the night. I was too hot and uncomfortable, so I stayed up looking at the sky. I saw a pattern of lights fly down on the nearby lake and almost immediately shoot away. As a kid I just assumed it was a helicopter, but it wasn't until years later that I realized that it made no noise whatsoever.
