One question yesterday was who else died on Prigozhin's plane.
So far, the answer appears to be "a bunch of thugs" (with the *possible* exception of the flight crew).
Wagner co-founder and neo-Nazi Utkin was on board, as was Wagner's chief financier. The rest of the passengers seem to have been Prigozhin's Wagner bodyguard.
The only people whose Wagner status isn't clear seem to be the 3 flight crew. They may or may not have been loyalists.
