Even the most powerful warplanes in the world can be prohibited to fly due to glitches. The entire fleet of the US Air Force Stealth Fighters are grounded due to problems with oxygen and power systems.
The report quoted Air Force sources as saying that they have linked the fault with a fatal crash last November.
Last week, test flights for the newer F-35 Joint Strike Fighters, which are made by Lockheed Martin, were suspended because of a valve problem in the plane’s integrated power system.
Test flights for F-22 Raptors have been suspended since May, and production has been put on hold because of a suspected problem with oxygen, Daily Mail said.
“It is third time this year the aircraft have been grounded, and there is no indication as to when tests will resume,” the report said adding that pilots have been told to return to their home stations until the jets are allowed to fly again.
