Actually the antigravity effect of rotating superconducting magnets was first recognized by Richard Pearse of New Zealand in May 1972. In an ingenious helicopter craft of his own design he slipped the surley bonds of earth from his farm workshop and flew several aerobatic routines finally landing in the road outside his farm gate. I know this because I read about it on an internet site and there were interviews there with people in 1997 that had seen it who described it in their own words.
Boeing is suppressing this, just another example of the Americans taking over aviation and keeping rightful recognition from a brilliant and underappreciated Kiwi. Looks like they are co-opting the Russians too. Shameless Yanks!!!
