US intelligence officials were ordered to compile a dossier for Congress after a flurry of videos filmed by US Navy and Air Force personnel were leaked.
The now-defunct Ministry of Defence division, which was axed in 2009 after nearly 60 years of official research and investigations, could once again relaunch depending on the findings of a looming Pentagon report into UFOs.
Speaking exclusively to The Telegraph, the source said: “I think that if there was enough evidence to suggest that there was something, and that we needed to do it as well as the US, then of course we’d think about it. We’d look at it. There’s all sorts of things that we wouldn’t rule out, and this would certainly be one of them.”
The source stressed that the constantly evolving nature of emerging science and technology “can suddenly open up whole new universes” and it was important to ensure the UK does not lose sight of the need to “identify [and] track objects in space and in our airspace”.
RAF Flyingdales tracks objects through space and the source said it could work alongside the US in future.
It comes after Lord Black asked the Government this month if it had any role in the US Task Force and whether there had been any information exchange.
Defence Minister Baroness Goldie said the UK “does not have a role” with the Task Force and “has not contributed” to the US report, though added the MoD is aware of it but can’t comment further until it is released.
UFOs – now more commonly referred to in scientific and intelligence circles as Unidentified Aerial Phenomena (UAP) – have stepped from being fringe conspiracy theories to a genuine security concern.
