He was on again Sunday night May 31, 2013 ... actually Monday April 01, 2013 with George Knapp.
Bigelow said he wasn't in support of the disclosure movement and thought it was important to differentiate between Disclosure ( of all the details ) and official confirmation ( that alien craft are real ), but didn't elaborate on it that much. Knapp mentioned that Bigelow once had a sighting of his own ( see quote from rense below for details ).
Knapp didn't ask if Bigelow's so-called "outside the box scientists" had made any progress on cracking UFO propulsion, but asked what his research in general has produced. Bigelow dodged the direct answer, but did talk about his general interest in the subject and mentioned that he is convinced because of what he and other people have seen ... probably an allusion to his own sighting.
Bigelow confirmed that behind closed doors powerful people in the circles that he travels in take the subject of UFOs very seriously. However he didn't go into much detail about who those people are.
They talked about the donations Bigelow has made to MUFON and CUFOS that led to allegations that he's part of a more shadowy "cabal" ( Bigelow pretty much dodged the whole issue ).
They talked a bit about the Skinwalker Ranch and he denied anyone has been hurt on the ranch. He also said that the research he's done, although "extraordinary" and has helped them "learn a lot", has also resulted in them "learning nothing". Knapp didn't probe for any further info ( getting lazy George? )
Bigelow commented briefly about how the prevailing attitude in the west about UFOs that leads to ridicule and scientists staying away from ufology puts us at risk of being left behind by other nations that spend the time and money to figure it out.
He also talked about a deal he's made with NASA to participate in their space program: NASA Deal for Inflatable Space Station Room | Bigelow Aerospace | Space.com
