Who passed away first, Manfred von Richthofen or Cedric Popkin ?
Cedric Popkin Cedric Bassett Popkin (Born 20 June 1890, died 26 January 1968) is considered the person most likely to have killed German ace Manfred von Richthofen — also known as the "Red Baron" — on 21 April 1918. Popkin was an anti-aircraft (AA) machine gunner with the First Australian Imperial Force (AIF), during World War I.
Sergei Preminin Sergei Anatolievich Preminin (Russian: Сергей Анатольевич Преминин, 18 October 1965 – 3 October 1986) was a Soviet Russian sailor who, after an explosion aboard nuclear submarine "K-219", prevented an impending nuclear meltdown by manually forcing damaged control rods into place. He was, however, unable to exit the reactor compartment because the hatch had jammed due to increased pressure, and died.
