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.

quote: But it was no match for a computer glitch that left six of them high above the Pacific Ocean, deaf, dumb and blind as they headed to their first deployment. So what happened? We turn to a man who's at home in the cockpit, Retired Air Force Major General Don Shepperd. Don, let me set the scene. These F-22s, eight of them, were headed from Hickam (ph) Air Force base in Hawaii to an (INAUDIBLE) Air Force base in Japan. They were approaching the international date line, pick it up from there."

If we'd put our efforts into improving the living conditions and job prospects of all the incredibly poor people in these countries, terrorism wouldn't be the problem it is today

quote: the government of this crap country blows away money in order to justify the need for more money. Our military needs more people in it to shoot people in the face on the ground at 10 meters or less. I dont see this 125 million dollar raptor helping anything in baghdad. I do see its development and per unit price as robbing me of my weekly paycheck.
