I may have to withdraw my Roswell comment. I cannot find the information that led me to that conclusion. Its quite possible it was this article by Kevin Randle (blogsport) that was implanted in my memory.
On Friday, July 25, Mitchell had the opportunity to clear up some of these misconceptions when he appeared on BlogTalkRadio’s ShapeShifting, hosted by Lisa Bonnice. He did say there was a cover up at Roswell, but also suggested that NASA knew nothing about it, or rather he had no information to suggest that NASA knew about it.
In response to one of Bonnice’s questions about Roswell, Mitchell said:
I was talking about the Roswell incident, the Roswell visitation primarily, but there have been many others that have been reported that I have no personal awareness of but that was the one that I was really talking about... and my information comes from what I call "the old timers," because I grew up in the Roswell area and when I went to the moon, some of the old timers from that period, some locals, and others military and intelligence people, who were under rather severe oaths to not reveal any of this and kind of wanted to get their conscience clear and off their chests before they passed on, selected me and said, independently - this wasn't a group effort - independently that maybe I might be a safe person to tell their story to. And all of them confirmed, and what I'm saying is they confirmed the Roswell incident was a real incident and they in some way had some part in it that they wanted to talk about.
Mitchell continued by saying:
Well, that the crash of an alien spacecraft in the Roswell area was a real event and much of the lore, I can't say all of the lore, but much of the fact that dead bodies were recovered and live ones were recovered, that they were not of this world, was the story. And of course it was reported in the Roswell Daily Record one day and promptly denied the next day and a cover story of a weather balloon, and that was pure nonsense. That was a cover-up.
Later, Mitchell told Irene Klotz from the Discovery Channel:
Subsequent to that, I did take my story to the Pentagon - not NASA, but the Pentagon - and asked for a meeting with the Intelligence Committee of the Joint Chiefs of Staff and got it. And told them my story and what I know and eventually had that confirmed by the admiral that I spoke with, that indeed what I was saying was true.
At first glance this actually supports my initial comment but there are some problems with this summary by Kevin which puts the case across with cherry picked elements of the interview, leaving context somewhat missed IMO.
I do think that Edgar has also made it clear that he believes the cover up is by a group of individuals as opposed to a collective organisational directive. I think it may be possible to establish if he considers some of these individuals to be within NASA as well as Goverment
