F-22 to fly again  (Source: USAF)
Raptor set to fly above 50,000 as restriction lifts

The grounding of the USAF F-22 Raptor fleet has dragged on for months as the investigation into what caused issues with the onboard oxygen generation system were investigated. At this point, there is still no clear answer on what gave multiple pilots hypoxia-like symptoms during flights. Affected pilots in several instances were found to have toxins in their blood.

Last week, reports indicated that USAF chief Gen. Norton Schwartz would be 
given options to grant flight status back to the F-22 fleet. Schwartz has approved a plan that will allow the 160 F-22 aircraft in the fleet to fly above 50,000 feet according to Defense News. The Raptor has a 60,000-foot ceiling.

The life support systems will be inspected daily on all of the aircraft, and all the systems will be extensively inspected before any of the jets take to the skies. The plan also calls for F-22 pilots to undergo physiological tests and to have additional protective equipment when they fly. Exactly what the extra equipment would be is unknown.

"We now have enough insight from recent studies and investigations that a return to flight is prudent and appropriate," Schwartz said. "We're managing the risks with our aircrews, and we're continuing to study the F-22's oxygen systems and collect data to improve its performance." 

As the F-22 fleet is preparing to return to the skies, the long-delayed and over budget F-35 fighter is again 
under pressure. USAF Secretary Michael Donley pledged support to the F-35 on September 19. However, with budget cuts coming and Washington looking for everything they can find to cut costs, Donley didn’t offer answers to what functionalities on the F-35 the USAF would be willing to lose to bring the cost of the fighters down.

Donley said that it would be difficult to eliminate core functionality from the program. "There are 12 core functions in the Air Force, there are none that we can just jettison," Donley said. "Each of those core functions is performing an important mission not just for the Air Force but the joint team."

Lockheed Martin says that as of now the F-35B STOVL version of the fighter is ahead on flight testing slightly and will be heading to sea trials in the first week of October if all goes as planned. The carrier-based F-35C will start sea trials next spring according to officials.

And fighter UAV/drone technology probably won't work completely right for the first generation anyway, and probably even second generation will be supplemented by piloted planes.

And F-22 might be 20 years old (based on its project inception), but if this is the case, any other fighter available in quantities is 30 or 40 years old. The Chinese J-20 has ONE built (by what everybody knows), the russian PAK-FA also has only a few built.
So yes, you Americans are using a 20-years old fighter against everybody's 40-years old fighters
