Dr Steven Greer of the disclosure project[1] recently made a dvd, called 'Unacknowledged'. It's been #one on iTunes documentary (apparently) for a while.
In it he talks about 'Unacknowledged Special Access Projects' (USAPs), which basically are illegal. The core of these USAPs is the UFO issue and he has countless witness testimonies from irrefutable military and private personnel, and has advised many people in Washington (CIA director, president elects) about them and they are generally amazed (apparently).
One of the things he explicitly mentions (and has been doing so for years), is that there is a secret agenda and that False Flag UFO encounters will be released, which will allow the military industrial complex to continue enslaving humanity.
To the point: recently, he's been vocal to state that all these UFO reports in the media over the last few days are just preliminary Flase Flag UFO events, designed to confuse and obfuscate the real problem.
