Saw one as a kid in the 60’s over New Jersey, like a lot of people we tried to follow it in the family car (red Ford Fairlane 500), thinking it came down locally. It exploded over Alaska. Appeared red and green, seemed to be spiraling or tumbling a bit, made a loud whistling sound, left a smoke trail I remember it clearly today. Some people reported seeing it as a spacecraft with aliens looking out the windows.
saw one in MI earlier this year, never did find out anything about it.
