Supposedly, on 29JAN2022 a MiG-31 (NATO reporting name Foxhound) crashed in Novgorod Oblast.

Unconfirmed reports say the plane was trying to take off but could not generate the speed necessary, running off the runway and bouncing off a snow drift.

Looking at the photos (source unknown) it is clear that there was a fire involving the rear cockpit, which caused the forward cockpit and fuselage to drop off.

It is common for MiG-31s to crash, usually blamed on “technical malfunction”.
