According to a letter from Secretary Panetta's office – effective immediately – the F-22 Raptors have to stay close to potential landing zones.
Last week, we told you about two Langley pilots who were refusing to fly the F-22 raptors because they couldn't rely on the oxygen supply. They suffered from dizziness, blackouts and other hypoxia symptoms in the cockpit.
The Air Force has been unable to determine the cause of the problem.
Today, in addition to the limits on flight distance, Panetta also ordered the Air Force to work faster to install an automatic backup oxygen system in every raptor.
He's also ordering the Air Force to work with NASA and the Navy to get to the bottom of the mystery.
He wants a progress report from the Air Force every month.
Virginia Senator Mark Warner met with the whistleblower pilots last week and he wants more from the Pentagon.
