A couple of days ago, a Scottish tabloid reported that a man managed to capture Nessie on a video captured by a drone that was recording his kayaking adventures.
In the original video on Youtube, now removed by its creator, there seems to be some sort of underwater object rising into visibility below the surface of the water, but what is it? From the context of the rest of the video, I doubt that it was a deliberate hoax; the author of the video claims not to have noticed it until after the video was uploaded and the commenters of the video pointed it out.
Since there have been numerous studies debunking the existence of Nessie, I doubt that it's any sort of large unknown animal, but what could it be?
