F-22 Fighter Jet

The Air Force and the Navy are rolling out new hardware and software for their trainer aircraft to stop the oxygen-deprivation problems that have plagued pilots for several years.

The devastation of Tyndall Air Force Base, where 17 grounded F-22 stealth fighters were damaged in the storm, points to American air power’s vulnerability in major hurricanes.

The Police Department blamed military F-22s. But Norad said the jets in place for the United Nations General Assembly did not produce a sonic boom.

The F-22 Raptor, the most advanced fighter jet, which has had oxygen problems, will still have some restrictions on its flight.

At a time of budget cuts, the Pentagon needs to ensure that every defense dollar is spent wisely. Yet problems with two major jets show it is far from that goal.

The Air Force said Thursday that it had determined why two more pilots recently experienced oxygen problems in the F-22 Raptor, the stealthy fighter jet.

Senator Mark Warner and Representative Adam Kinzinger are seeking answers from the Air Force on the problems experienced by pilots on the world’s most expensive fighter jet.

There seemed to be a step forward on oxygen flow problems last month, but then a pilot told of discomfort from intermittent airflow into his mask during flight.

Defense Secretary Leon E. Panetta, responding to a “60 Minutes” report, ordered flights to remain within safe proximity of airports.

Manufacturing delays, rising costs and the rapid increase in capabilities of unmanned aircraft have dulled the luster from the once-thriving industry of military aircraft manufacturing.
