Air Force is replacing handles that engage the F-22 Raptor fighter jet's emergency oxygen system after pilots reported feeling lightheaded and the death of a captain whose $143 million aircraft took a nosedive into a mountain range in Alaska. Capt. Jeffrey Haney was killed in November 2010 during a night mission about 100 miles north of Anchorage. An accident investigation found that the plane's controls and switches contributed to the crash, particularly an emergency oxygen system activation ring on the back edge of the ejection seat. The report found that the two-step process to manually activate the system required the pilot to pull the green ring up and out of the retaining slot and then pull it directly forward. The Air Force says the latter move may have the same force as pulling a 40- or more pound weight. While the ring is attached to the seat by a lanyard, if it is dropped it can fall between the seats, making it difficult to retrieve, especially if the pilot is flying at night and wearing bulky winter clothing. The problem with the system was identified by an independent scientific advisory board that studied the jet's safety issues. It was identified as one of the critical items to be fixed, according to public affairs at Luke Air Force Base in Arizona, which came up with the new, safer handles. The modification makes it easier for the pilot to access the handle, the military says. The Air Force has ordered 200 handles at a cost of $47 each. They have already been installed in Joint Base Elmendorf-Richardson's 40 F-22s, the Anchorage base that Haney, 31, was attempting to return to when he crashed during a night-time training mission.

“The Air Force has ordered 200 handles at a cost of $47 each”
It’s the shipping and handling.
Okay, they fixed the EMERGENCY oxygen handle. For when they need EMERGENCY oxygen. What about the OBOGS system that is causing the pilots to become hypoxic/dizzy/lethargic?
