Will America's hottest warplane make it to this June's Paris Air Show? The Commerce Dept. is urging the Air Force to send an F-117A stealth attack plane to the annual arms bazaar. The Air Force, however, is still trying to keep the plane under wraps and has allowed it out of the U. S. only for combat missions. Even if the F-117A makes an appearance in Paris, it, unlike everything else at the show, won't be for sale.
