But to tell you the truth Mac'...I can't say that i'm sad about the announcement myself!...for the simple reason that I have never thought that the 'UFO Desk' at Whitehall was anything more than a Front created solely to placate the general public's thirst for knowledge!..and that the real investigatory actions are, and always have been performed behind some Very Thick doors!

1963, some very thick doors indeed.
I remember retired Bluebook Chief Colonel Robert Friend once said that during his tenure there were 'classified intelligence channels for reporting UFO's that completely bypassed Bluebook' and government docs also exist which state that 'UFO reports that were a threat to national security weren't even part of the Bluebook system' (

Also, when it comes to the MOD I always found this quote from one of their senior officials to be quite a revealing one..
Quote
"Here we had a number of object seen coming in across the North Sea on coastal radar. It looked like a Russian mistake. Jet aircraft were scrambled. The objects were travelling at quite impossible speeds like 4-5000 mph and then came to an abrupt halt near to one of these stations not very high up. Jet aircraft picked them up on aircraft radar. The objects then simply made rings round them."
"Inevitably this led to the sort of enquiry which you would put in hand if you had any military responsibilities. Had something gone wrong with ground radar or with aircraft radar? We experienced pilots going out of their minds? Were people having fantasies? We *had* to investigate cases of that kind. Over the years - although there were not an enormous number of such cases - there were a sufficient number to persuade me, and a number of air staff friends with whom I had to work, that something was going on, sporadically, in British airspace which we could not explain."
"But we did not particularly want to make public statements about that. Not for something that we had no explanation."
Ralph Noyes,Senior Official with British Air Ministry - retired as Under Secretary of State in 1977

Here's what Jacques Vallee also had to say about censorship and manipulation of UFO data when governments 'encouraged secret briefings' and 'funded classified research' whilst all the time pretending to the public the subject was nonsense - pretty interesting statement, especially from a man of his calibre.

"
Governments took notice, organizing task forces, encouraging secret briefings and study groups, funding classified research and all the time denying before the public that any of the phenomena might be real. The major revelation of these Diaries may be the demonstration of how the scientific community was misled by the government, how the best data were kept hidden, and how the public record was shamelessly manipulated."
