Another YouTube video of what appears to be a spinning UFO over Amsterdam.
Original video no longer available, this video is from 2013
The video was taken by a guy working on a school assignment on 9th June 2009. He noticed the object moving above the city, and zoomed in to center the object in the video. The object appears to be a three-sided object that is spinning, it then rather suspiciously disappears in a large flash.
