Britain has a stockpile of aircraft, drones and weapons that could be used to fight aliens in the event of an invasion from space, according to the government's former UFO adviser.
In an interview with MSN, Nick Pope, who worked for the Ministry of Defence for 21 years, said that while Britain doesn't have a war plan, it certainly had sophisticated enough weaponry to defend itself.
Mr Pope, whose job it was to advise on the threat posed by other life forms, said that in the event of an attack he expected that we would "quickly adapt our plans for other more current war scenarios."
At present, he said, there was no special organisation like Torchwood, the alien-hunting team from the BBC science fiction series of the same name, but he said he was sure that in the event of attack an operation could be set up quickly and efficiently. World nations would probably pool their technology together like in films such as Independence Day.
