The USAF's new F-22 ran into a nasty software bug over the Pacific when eight of these fighters were making the type's first deployment overseas. In the words of Major General (retired) Don Shepperd, CNN military consultant, "At the international date line, whoops, all systems dumped and when I say all systems, I mean all systems, their navigation, part of their communications, their fuel systems... they could have been in real trouble... they tried to reset their systems, couldn't get them reset. The tankers brought them back to Hawaii... They are on a 12 to 15-hour flight from Hawaii to Okinawa, but all their systems dumped. They needed help. Had they gotten separated from their tankers or had the weather been bad, they had no attitude reference. They had no communications or navigation. They would have turned around and probably could have found the Hawaiian Islands." http://transcripts.cnn.com/TRANSCRIPTS/0702/24/tww.01.html (The relevant part is about halfway through the transcript, right after a commercial break.) Years ago, when I worked in the B-2 flight test program, I remember we did one flight across the Equator for the express purpose of verifying that nothing would go haywire in south latitudes. Can't remember if the same was done for east longitudes. -- I block messages that contain attachments or HTML. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
