Flight Sergeant Nicholas Stephen Alkemade (1922–1987) was a rear gunner in Royal Air Force Avro Lancaster heavy bombers during World War II, who survived—without a parachute—a fall of 18,000 feet (5,500 m) when abandoning his out-of-control, burning aircraft over Germany. His fall was broken by pine trees and a soft snow cover on the ground. He was able to move his arms and legs and suffered only a sprained leg. The Lancaster crashed in flames, killing pilot Jack Newman and three other members of the crew. They are buried in the CWGC's Hanover War Cemetery.
