Likely ran out of fuel. That model of Mig is a flying fuel tank, and if it had any left in it, it wouuld have burned like a blow torch.Note there is no sign of fire. The pilot pancaked it in and hit a farm hut.
Good observation. I’m buyin’ it. Makes you wonder about China’s radar capabilities if any of this is true. I don’t believe much of anything reported from China, which is a rare occurrence in and of itself.
The pilot probably tried to bail out... only to realize that their ejection seat hadn’t been worked on since the Norks bought the MiG-21 from the USSR all those many years again.
Then died on impact.
