This object was picked up accidentally on by a passenger on a KLM flight from Amsterdam to Dallas on March 17. The UFO appears in the first few seconds of the video, but another YouTuber has provided a stabilized image that contains enough digital information to make it clear that this is not a balloon. It was hovering in heavily monitored airspace but received no official notice that was shared with the public. To see the stabilized footage, click here.
