The two Virginia Air National Guard pilots who just days ago told the nation that the F-22 fighter wasn't currently safe to fly now want to resume flying the jet.
The pilots are more comfortable about operating the aircraft now that the Air Force has removed a charcoal filter from the jet that service officials had installed to monitor for contaminants in Raptor pilots' air supply, reported (*) 'The Daily Press' of Newport News, Va., on May 9, citing the two pilots' attorney.
The two pilots thought this filter—meant to help identify why some F-22 pilots, including both of them, have experienced hypoxia-like symptoms in the cockpit—was making it harder for them to breathe, according to the newspaper.
The Air Force leadership is treating both 192nd Fighter Wing pilots—Maj. Jeremy Gordon and Capt. Josh Wilson—as whistleblowers, USAF headquarters spokesman Lt. Col. John Dorrian told the 'Daily Report'.
This means they are protected from punishment under federal law for appearing on CBS News' 60 Minutes television broadcast on May 6 to air their concerns.

The Pentagon announced on Tuesday new safety precautions for its F-22 fighter jets -- including limiting how far they can fly away from airstrips -- after pilots experienced symptoms of oxygen deprivation aboard the advanced stealth aircraft.
U.S. Defense Secretary Leon Panetta believes the new precautions on the F-22s, built by Lockheed Martin, are sufficient to guarantee safety. But the Pentagon did not rule out again grounding the aircraft, if necessary.

A Lockheed Martin F-22 Raptor from Tyndall AFB, Florida, was damaged last Thursday evening during a training flight, the US Air Force confirms.
While the pilot is safe, the aircraft suffered more than $2 million in damage-which classifies the incident as a Class A mishap. The full extent and cost of the damage has yet to be determined, but the service expects that the aircraft will be repaired.
The aircraft was being flown by a student pilot transitioning to the Raptor from another aircraft type at the time of the accident. It was the pilot's second sortie in the jet after completing academic and simulator work.
The USAF is not able to offer any additional details due to an on-going investigation into the incident, but the mishap does not appear to be oxygen-related.
"There is no indication at this time that the life support system was related to the incident," the USAF says. "However, the investigation is on-going."
The USAF is not saying which tail number was involved in the incident. But the 43rd Fighter Squadron, which is the USAF's Raptor formal training unit, has 29 early production aircraft assigned to it.

F-22 Mishap at Tyndall Under Investigation
Air Force officials are releasing few details on a recent F-22 "mishap" at Tyndall AFB, Fla., pending the results of a safety investigation board review.
"Everything surrounding that incident is under investigation," Herman Bell, spokesman for Tyndall's 325th Fighter Wing, told the "Daily Report" June 8.
The wing trains new F-22 pilots.
The incident occurred on May 31 during an orientation course intended for new Raptor pilots to get familiar with the aircraft, said Bell.
Although he said it's not clear whether mechanical or pilot error caused the mishap, he noted that it was only the pilot's second solo F-22 flight.
The pilot was not injured, but the aircraft suffered "a number of scrapes on the bottom," leading maintainers to tow it from the scene, he said.
The F-22 is "still fully intact," noted Bell.
Officials are still assessing the repair costs, but Bell said he thought the accident likely would be classified as a Class A mishap.
These types of accidents involve more than $1 million in damages. "The individual walked away unharmed.
That's the important thing," said Bell.

http://www.flightglobal.com/news/articl ... ka-372957/USAF Raptors train with Eurofighters at Red Flag-Alaska
The US Air Force's Lockheed Martin F-22 Raptors are participating in their first Red Flag-Alaska war-games with German Eurofighter Typhoon fighters and other foreign aircraft.
Poland is flying its first Red Flag with its new F-16C/D Block 52 aircraft while Japan has brought its Boeing F-15J Eagles.
Pilots from the 3rd Wing's 525th Fighter Squadron and its reserve associate unit, 477th Fighter Group, are flying the Raptors during the exercise. The Typhoons, Raptors and Eagles are all flying as friendly "Blue forces" during the exercises.
"They are never on the Red side," says Major James Mixon, an exercise planner with the 353 Combat Training Squadron referring to the Raptors. The idea is to teach the visiting forces how to interact with the stealthy fifth-generation fighter, he says.
For the exercise, the Luftwaffe brought over eight Typhoons from Jagdgeschwader 74 to Eielson AFB, Alaska, says unit commander Col Andreas Pfeiffer.
For the Germans, the exercise affords a unique opportunity to training over the vast ranges found in Alaska. The ranges at the base offer the ability to replicate the latest surface-to-air threats while the USAF's 18th Aggressor squadron replicates enemy aircraft like the Russian Su-27, Su-30 and Chengdu J-10.
Pfeiffer says flying with the Raptor was an interesting experience.
"Its unique capabilities are overwhelming," Pfeiffer says.
Cosí peró non vale...eh!The Typhoons, Raptors and Eagles are all flying as friendly "Blue forces" during the exercises.

Ref: Jane's Defence WeeklyTYPHOON 'HOLDS ITS OWN' AGAINST RAPTOR
Immediately before Red Flag JG74 took part in Exercise 'Distant Frontier', which included eight one-on-one basic flying manoeuvre (BFM) sorties against US Air Force F-22A Raptor air superiority fighters. The aim was to help pilots of both types gain a fuller understanding of the capabilities, strengths and weaknesses of each other's aircraft in order to allow them to operate together more effectively during Red Flag (where both types were assigned to the 'Blue' force) and during any subsequent 'real world' coalition operations.
During the process the pilots of JG74 gained a real boost to their confidence, said Col Grüne. "There were two mornings where we flew against them 1v1. We pulled off all the tanks to get the most alpha [angle of attack]; the Eurofighter really is an animal with no tanks.
"We expected to perform less with the Eurofighter but we didn't ... they were as impressed by us as we were impressed by them."
Col Pfeiffer went into a little more detail. "In the dogfight the Eurofighter is at least as capable as the F-22, with some advantages in some aspects," he said. "This is without the helmet. The Raptor's unique capabilities are overwhelming, but as soon as you get to the merge, which is [admittedly] only a very small spectrum of air combat, the Typhoon doesn't necessarily have to fear the F-22 in all aspects. We gain energy better than the F-22 when we are slow, for example."
Red Flag demonstrated that the Typhoon had other advantages - being able to stay on station longer than the F-22, for example - but could not compete with the Raptor's dominance in the beyond-visual-range (BVR) arena.
Both sides were coy about the relative kill:loss ratio gained during the Typhoon/F-22 BFM sorties, but Col Grüne was upbeat. "The only thing I can say is that I agreed to put out some whisky if they came back with some good performances ... and I paid for quite a lot of whisky," he said.
