Could it be time to call in Mulder and Scully?
An Unidentified Flying Object (UFO) has been spotted over the Bristol Channel sparking online speculation about Little Green Men.
It is unlikely a crew of errant aliens were enjoying a whistle-stop tour of Great Britain but the UFO sighting has left many Twitter users speculating about what it could be.
Any suggestion?? Nothing seen by local ATC... ?? pic.twitter.com/Hu07DLmn3z— NPAS St Athan (@NPAS_StAthan) September 23, 2016
The National Police Air Service St Athan in South Wales tweeted footage of the UFO explaining it was not spotted by local air traffic control.
@NPAS_StAthan added the object was very hot and moving against the wind, tweeting: "Any suggestion [sic]?? Nothing seen by local ATC... ??"
They said it was unlikely to be a lantern, adding: "We really don't know [what it is] but doubt it was a lantern as it was going into the wind."
Replying to another user they posted: "Only slight problem is the amount of heat and it was travelling into wind?"
They also explained: "It was on Saturday night (September 24) about 21:30 and was spotted over the Bristol Channel at approx 1000ft.
"Our clock is out by one hour so it was pitch black. Tried on day camera, nothing seen. this clip is just a small part of the vid.
"Really difficult to judge the size but we filmed it for just over 7 minutes as we were coming back into land."
