Cone over Bermuda/Florida coast (between), Atlantic Ocean
A witness account on file, unevaluated. Most of the archive rests here, and honestly so.
The report, as filed
While looking out of the window of our airplane, I saw an object going straight into the sky and kind of blowing a feather shape cloud up in the air. The shape was sharp lined. After that, the feather shaped was "swirled" around 3 quarters of a circle around the object after which the object followed the shape in the opposite direction of where you usually see a white line behind a plane when high up. It was literally pushing the feather like shape direction Bermudas. The object had a beige like color, but I could not see a shape or anything...just a beige "thing" following the feather like shape it just threw out. It happened above the Atlantic Ocean between Bermudas and the Florida Coast line. Because the windows of the airplane had to be closed, I think I was the only one seeing it, sitting on the right side of the plane above the wings. It was a very strange experience.
