A video of what looks like a mysterious object floating off the coast of Ireland has emerged on YouTube.
The 70-second clip, which was recorded by an unnamed passenger seated in a plane en route to Prague from Dublin on 28 December, was uploaded by a YouTube user called mavi777.
The video of what mavi777 described as a "strange UFO" shows a perfectly circular object slowly hovering near the shoreline of Ireland.
The video has already gained more than 1,800 views, from both conspiracy enthusiasts as well as sceptics.
Some touted the video as "awesome" and "fantastic", with one user insisting that he managed to notice "some type of dust" pouring out of the mysterious object.
Others remained downbeat about the clip, claiming that the alleged UFO was little more than a "large circular reservoir" or "intake chamber".
