The U.S. Air Force will resume flights of Lockheed Martin Corp.’s F-22 Raptor this week, which has been grounded for four months after pilots suffered symptoms related to oxygen deprivation.
“We now have enough insight from recent studies and investigations that a return to flight is prudent and appropriate,” said Air Force Chief of Staff General Norton Schwartz in a written statement.
