Russian Air Force Lets MiG-31 Fly Again After Crash

The Russian Air Force will restart flight operations on Monday by its fleet of Mikoyan MiG-31 interceptor aircraft that were grounded earlier this month following a crash.
Two aircrew ejected safely from their MiG-31 in the far east of the country on December 14, after an apparent engine failure. The MiG-31 fleet was grounded two days later as a precautionary measure.
