All we ever heard was that there was an error in the study. Between you and I, it sounds very much like a coverup. It's a suspicion that gets voiced a lot in the UFO field about Bigelow and his research group, the Nevada-based National Institute for Discovery Science. His deep pockets give him access to a wealth of rumors and reports about weird happenings - but NIDS is notoriously stingy with its information. NIDS is a black hole.
Nobody seems to know what their real agenda is.
Nobody seems to know a whole lot about Bigelow either. His official NIDS bio describes him as a very wealthy philanthropist with his own aerospace company - currently working on a project to develop the first orbiting space hotel. In 1947, according to the Wall Street Journal, Bigelow's grandparents were buzzed by a glowing red UFO while driving through the Nevada desert late at night. We weren't allowed to publicize them without NIDS' permission. He bought out the owners on the condition that they keep mum about whatever they'd seen.
