The Brits are opening up their MoD UFO files, with 150 files to be released over the next 10 years.
I'd say the biggest UFO story worth looking at that these files could shed some light on is something that happened in 1981 over an RAF/USAF airbase (multiple witnesses, including high ranking military officials, physical evidence, radar signatures). Was it aliens? Soviets? Guards smoking pot? I don't know, but there is evidence that something unusual happened, maybe these files will shed some additional light on what really did happen back then.
Also, the Pope declared that it was ok to believe in aliens.
