Passengers aboard a Ryanair flight to Spain got a little more excitement than they bargained for when their pilot violently swerved the plane to avoid what can only be described as a UFO.
The video, reportedly taken by a Dutch passenger, shows the wing and then the plane dipping and finally a very fast black object flying under the wing.
You can then hear gasps and excited chatting from passengers as it becomes clear that a number of those on board witnessed the event.
The video was apparently sent into conspiracy website Lionsground, who then published it on their YouTube channel.
Even when slowed down it's remarkably difficult to actually make out the shape of the object although it's clear that it was larger than a bird and certainly faster moving.
There is of course the possibility that this was a cleverly created fake, planes do pull tight manoeuvres all the time and it wouldn't have been too difficult to simply animate an object passing at the moment the plane turns tightly.
While UFO sightings take place all the time, it's not often you get one that's supposedly caught from a plane.
It's also important to remember that UFO doesn't mean aliens, indeed conspiracy theorists are open to all possibilities from secret stealth fighters to the notion that actually Tony Stark does exist and yes, that's Iron Man.
For now though we're happy to have our brains pleasantly confused as we have literally no idea what this is.
