UFO enthusiasts received a boost when a former astronaut, Dr. Edgar Mitchell, claimed on a radio interview “that extra-terrestrials have visited Earth on several occasions”, but that there has been a cover up by governments for six decades. Mitchell was the sixth man to walk on the Moon.
The interviewer was predictably dumbfounded, and I noted that Mitchell’s comments coincided with the opening of the new X-Files movie. Here is a short clip from Mitchell’s interview.
A longer YouTube video of the interview is here:

NASA politely debunked Mitchell’s statements:

‘Dr Mitchell is a great American, but we do not share his opinions on this issue.’

I find Dr. Mitchell’s story hard to believe. It lacked credible detail. On the other hand, I will admit there are many strange stories out there, many of them from official sources like the British Government.
Britain’s Ministry of Defence claims to have revealed everything it knows about UFOs. I wrote a post on this - I even added a little Bajan touch with some Barbados sightings. See:
