Restrictions for F-22 ordered
The US Department of Defence has issued further safety procedures for its most advanced fighter jet F-22 after pilots complained of oxygen shortages during the flights and refused to fly the aircraft despite the assurance of Air Force leaders that the plane is safe.
US Defence Secretary Leon Panetta has also asked for a back-up oxygen system to be installed into the F-22 jets, and has limited the distance they travel from airstrips. The Air Force already grounded the planes last year for five months after pilots reported symptoms resulting from a lack of oxygen, such as nausea and blackouts.
The F-22, manufactured by Lockheed Martin, is considered the world’s most sophisticated fighter jet. It can reach supersonic speeds and is equipped with radar and sensors, enabling it to track and shoot enemy aircraft before being detected.
