This strange UFO phenomenon was filmed over Dover, the capital city of Delaware in United States on 10th September 2021.
Witness report: A bright ball like reddish smoke with single trail turning into 2 trails It was around 7:15 pm when my wife and I started to take a walk in our neighborhood. The sun was setting in the west with pink clouds in the distance. There was still blue sky left. That’s when I noticed what looked like a dark pink cloud by itself and out of place. I stopped to look at it and asked my wife if she saw it moving. She said yes. Then the cloud started to move slowly towards us and with a tail like a comet. Then it seem to turn away from us with 2 tails. It finally went from reddish to black then went into cloud cover and it was gone.
