Defense Secretary Leon E. Panetta has approved a plan to begin lifting flight restrictions that he placed on the Air Force's problem-plagued fleet of F-22 Raptor fighter jets. Since 2008, F-22 pilots have reported more than a dozen incidents in which they experienced hypoxia-like symptoms in the air. Hypoxia is a condition that can bring on nausea, headaches, fatigue or blackouts. In May, Panetta ordered that any flights in a F-22 “will remain within the proximity of potential landing locations to enable quick recovery and landing should the pilot encounter unanticipated physiological conditions during flight.

The Department of Defense inspector general has questioned an Air Force report of its investigation that blamed the pilot for the 2010 crash of an F-22 Raptor fighter jet. In its report released on Monday, the inspector general's office questioned the original findings of the Air Force's Accident Investigation Board (AIB) report on the F-22 crash. “The AIB Statement of Opinion regarding the cause of the mishap was not supported by the facts within the AIB report consistent with the clear and convincing standard of proof,” according to the inspector general's report.

Concerns about the Air Force's problem-plagued fleet of F-22 Raptor fighter jets led Defense Secretary Leon E. Panetta to restrict flights of the aircraft because of problems with its oxygen systems that can cause its pilots to become disoriented mid-flight. In addition, Panetta wants a monthly progress report on the investigation into the root cause of the F-22's oxygen problems and ordered the Air Force to speed up the installation of an automatic backup oxygen system. Panetta also called on Navy and NASA personnel to find a solution.

The U.S. Air Force's F-22 Raptor fighter jets have been cleared for takeoff after a government safety investigation grounded the entire fleet for more than four months. The Air Force said that all 170 F-22s will be inspected before flight operations resume. The fleet was put out of service May 3 after a dozen incidents since April 2008 in which pilots' oxygen was cut off. It is the latest issue for the F-22, which cost an estimated $412 million each, according to the U.S. Government Accountability Office's latest report, and have not been used in combat since entering service in 2005.

Oxygen problems that have plagued the Air Force's fleet of F-22 Raptor fighter jets may be worse than previously disclosed, according to new information released by two members of Congress. F-22 pilots have reported dozens of incidents in which the jet's systems weren't feeding them enough oxygen, causing hypoxia-like symptoms in the air. Hypoxia is a condition resulting from a deficiency of oxygen reaching tissues of the body that can cause nausea, headaches, fatigue or even blackouts.

The Air Force will modify the handle that engages the emergency oxygen system in its entire fleet of F-22 Raptor fighter jets after a report found that it played a role in a crash that killed one of its top aviators. The changes come as Anna Haney, the pilot's widow, filed a wrongful-death lawsuit againstLockheed Martin Corp.and subcontractors that designed and built the nation's most expensive fighter jet. Capt. Jeff Haney, 31, died when his F-22 crashed in the Alaskan wilderness in November 2010.
