Six Lockheed F-22 Raptors have Y2K-esque glitch of their own over the Pacific

Lockheed’s F-22 Raptor is the most advanced fighter in the world with its stealth capabilities, advanced radar, state of the art weapons systems and ultra-efficient turbofans which allow the F-22 to "supercruise" at supersonic speeds without an afterburner. The Raptor has gone up against the best that the US Air Force and Navy has to offer taking out F-15s, F-16s and F/A-18 Super Hornets during simulated war games in Alaska. The Raptor-led "Blue Air" team was able to rack up an impressive 241-to-2 kill ratio during the exercise against the "Red Air" threat -- the two kills on the blue team were from the 30-year old F-15 teammates and not the new Raptors.

But while the simulated war games were a somewhat easy feat for the Raptor, something more mundane was able to cripple six aircraft on a 12 to 15 hours flight from Hawaii to Kadena Air Base in Okinawa, Japan. The U.S. Air Force's mighty Raptor was felled by the International Date Line (IDL).

When the group of Raptors crossed over the IDL, multiple computer systems crashed on the planes. Everything from fuel subsystems, to navigation and partial communications were completely taken offline. Numerous attempts were made to "reboot" the systems to no avail.

Luckily for the Raptors, there were no weather issues that day so visibility was not a problem. Also, the Raptors had their refueling tankers as guide dogs to "carry" them back to safety. "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," said Retired Air Force Major General Don Shepperd. "They would have turned around and probably could have found the Hawaiian Islands. But if the weather had been bad on approach, there could have been real trouble.”

"The tankers brought them back to Hawaii. This could have been real serious. It certainly could have been real serious if the weather had been bad," Shepperd continued. "It turned out OK. It was fixed in 48 hours. It was a computer glitch in the millions of lines of code, somebody made an error in a couple lines of the code and everything goes."

Luckily for the pilots behind the controls of the Raptors, they were not involved in a combat situation. Had they been, it could have been a disastrous folly by the U.S. Air Force to have to admit that their aircraft which cost $125+ million USD apiece were knocked out of the sky due to a few lines of computer code. "And luckily this time we found out about it before combat. We got it fixed with tiger teams in about 48 hours and the airplanes were flying again, completed their deployment. But this could have been real serious in combat," said Shepperd.

Yes i did, and in the article it also states that BA were making a profit. Also if it was such a money-loser why wouldn't BA sell their Concorde's to Virgin? Surely they should have been happy to get such a liability off their balance sheet?

In any case the comments that you are quoting are from recent history, in 1976 the political landscape was totally different. The princiapal reason why American airlines did not buy Concorde initially was because of the announced American SST project that was rushed out in case America got left behind in the supersonic age, not because of cost.

As to your last point i've already said, why would Boeing want to invest such huge amounts of money when they had most of the market wrapped up with various versions of the 747?

If BA can't make it work, then why would Virgin have any better luck? Virgin can't change the cost and availability of spare parts, for example.

I'm sure Boeing also noticed the fact that half of the Concordes ever built were never purchased, and were eventually given away to the airlines. Having only covered about 1/2 your costs is not any want to achieve "economic viability." Maybe that's just an American thing, though. :o)

Well....

Boeing may not be interested in producing another supersonic passenger plane... but Boeing isn't the only game in town, either. :o)

Take a gander at Lockheed's new toy:

What do you know? I guess the innovations that they make for the millitary actually do trickle down into the consumer marketspace. ;)

It's actually estimated to start flying in 2011. It would be really cool if Lockheed could pull this project through and they started getting popular so they could be mass produced. Maybe we could start seeing supersonic passenger planes for the slightly less wealthy of us. We can hope... :D
