Did Cheney Cover Up Losing Three Nukes?

Wayne Madsen is telling a head spinning tale of lies, lost nukes, black market smuggling and international intrigue worthy of James Bond. Nukes being clandestinely sold isn't such a far fetched idea, after all there was plenty of stuff from the Soviet arsenal that went missing, but this story seems to tie in to a lot other goings on:

"WMR has been told by a well-placed intelligence source in Britain that in early February 1991, the Pentagon sent out an emergency message rarely seen: three "Broken Arrows," or lost nuclear weapons in U.S. possession, were jettisoned in the Indian Ocean by a U.S. Air Force B-52, which had caught fire en route from Diego Garcia with three weapons of mass destruction being transported from South Africa after that nation began dismantling its nuclear weapons program. On a return emergency route back to the U.S. base on Diego Garcia, the crew of the aircraft disposed of the bombs to avoid a cook off of their heat-triggered fuses. The B-52 later crashed. The three bombs landed in shallow waters off the Somali coast. Rather than retrieve the weapons, Cheney and the Bush I administration sat on their hands."
