U.S. Air Force fixes computer glitches in 87 F-22s

The six Raptors were participating in an inaugural 12-hour flight from Hawaii to Kadena Air Base in Okinawa, Japan on Feb. 10 when a "navigation anomaly" maimed several computer systems on the aircraft, an Air Force colonel said.
The computer glitch, which occurred as aircraft crossed the International Date Line, crippled navigation systems and hindered communications.
One pilot was able to contact contractor Lockheed Martin to troubleshoot the error during the flight, the Air Force said. Several pilots attempted to reboot the system with no success.
Luckily for the Raptors, there were no weather issues that day so visibility was not a problem which meant that with their refueling tankers as guide dogs, they were able to safely return to Hawaii.
"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."
F-22 engineers and maintainers were able to locate the problem within hours and fixed the glitch in a matter of days on the aircraft. After successful testing, the aircraft continued their planned first overseas deployment to Kadena.
It was a computer glitch in the approximately 1.7 million lines of code. Somebody makes an error in a couple lines of the code and everything goes.
It is common for pilots to experience operational problems during initial deployments and there are no plans to conduct further testing on the F-22 Raptor.
The Raptor, with a price tags of roughly $70 billion including development costs, has endured periodic delays and political attacks. Initial plans called for 750, but only 183 are now slated to be built under the proposed 2007 fiscal defense budget.
I swear to God, who the hell released this type of information?????
LM: Ring, Ring - Lockheed Martin, Help Desk.
F22: Yeah, my systems are down!
LM: Sure, sorry about that. I'll need to get your name, call sign and extension to log your problem. All of our support people are tied up on other calls at this time. CLICK!
"... Had they gotten separated from their tankers or had the weather been bad, they had no attitude reference. They had no communications or navigation..."
That's what's called 'flying by the seat of your pants' - like they did in WWI bi-planes (except at mach 2, heheh).
"Initial plans called for 750, but only 183 are now slated to be built under the proposed 2007 fiscal defense budget."
That's so sad - we need those 750 - and even twice that would be better. From the reviews I've read, the F-22 is an awesome bird.
Should this be public information ?
