There were many senior leaders on the flight: Prigozhin, Utkin (early founder, commander), Chekalov (economic & security leader), Makaryan, Propustin, Totmin, Matuseev (all various commanders). While this seems super dumb to have all these folks on the same flight at the same time, apparently they were. With this much senior leadership now suddenly gone, the Wagner group may be struggling to get their own house in order before they can take organizational action.
