(Reuters) - An Embraer Legacy 600 executive jet, believed to have carried Wagner mercenary chief Yevgeny Prigozhin to his death on Wednesday, showed no sign of problem until a precipitous drop in its final 30 seconds, according to flight-tracking data.

Rosaviatsia, Russia's aviation agency said Prigozhin, who led an aborted mutiny in June, was one of 10 people on board the downed plane. It was traveling from Moscow to St. Petersburg when it crashed near the village of Kuzhenkino in the Tver Region, Russia's emergency situations ministry said.
