I believe a former Canadian Minister of Defence, Paul Hellyer started to let the cat out of the bag so to speak when he made a public statement about governments should be able to use UFO Technology to save the world from global warming etc. I wrote about it Here At that time, I postulated that the head of a government defence department would be one person who would have knowledge of UFO's if there was any to have.
Hellyer would at least be privy to the reports, the claims, and the findings of government investigations. It would be likely that he wasn't just making it up. Strangely enough, it didn't get a lot of press time....wonder why? Was he dismissed as someone gone crazy? The rantings of an old man? That of course is the danger of mentioning something like that in a public venue. Of course, there is also the possiblity that he was asked to remember his vow of secrecy by those in power.
Speaking of UFO's here is a series of videos about UFO's and the year 2012.
Here is Part 2
Here is Part 3
Further to the above, here is an interview with Paola Harris, the UFO investigator that spoke to Paul Hellyer regarding his UFO views. In this video, Paola is being interviewed for Coast To Coast AM, an American radio show.
