I just have trouble believing that the probably thousands of people both government and private involved in such programs that no doubt exist across every major power on earth (unless for whatever reason UFOs choose to only fly around and crash into the continental US) have all managed to stay quiet about something of this magnitude for decades (or damn near 100 years if his claim of it starting in the 1930s is to be believed)
Not to mention that, simultaneously, the government(s) is powerful enough to successfully suppress this information for a hundred years, while some how also failing to keep somebody from testifying about it in a publicly televised congressional hearing
Attached to him, I hope
