Leonid Tsederbaum was the navigator in Boris Gribkov's Tu-4 during World War III. He was a Jew, which Gribkov privately noted on multiple occasions. He also became Gribkov's self-appointed conscience and made vague criticisms of the USSR throughout the war. In mid-April, the crew transferred to an airfield outside of Leningrad. They took a train to Moscow, and were able to see the damage to the heart of the city first hand. They were flown the rest of the way, and could also see the damage inflicted on Leningrad. Tsederbaum quietly noted that their crew had done the same thing to Seattle.
