[Don't start paragraphs with From, please! --CDR] [F]rom what I've read (lots of YF-22 updates from Lockheed, whom I worked on a clinic team for this year) the YF-23 was indeed more stealthy than the YF-22 but both planes met the Air Force's specs for stealthiness. The YF-22 has vectored thrust which probably accounted for the superior performance mentioned in the announcement. And the price tag was lower. >Still, both planes are a tribute to American technology, (they better >be at 51 million a copy). I just wish we could have them both. Hey, >maybe the Navy would be interested in the other. I think the reason for picking one over the other is to cut down on the training, maintenance, and spare parts problems you'd have by operating two different planes to fill one role. -- John H.
