Air Force Risk

"For two months, the U.S. Air Force has been without its newest jet fighter. But the situation could be far worse — and likely will be in coming years as the Air Force trades the robustness of a diverse fighter fleet for the supposed cost savings of a more homogenous one.

On May 3, 2011, the Air Force announced it was temporarily banning the Lockheed Martin F-22 from routine flying while the flying branch investigated a series of incidents possible related to the fighter’s oxygen-generation system. The ban was later extended indefinitely, and has forced Lockheed to suspend deliveries of new Raptors."
