In 1939, Geoffrey de Havilland submitted a proposal to the Air Ministry for a twin-engine bomber with no defensive armament, made almost entirely of wood.
They said no.
The objections were logical: wood was not a proper material for a modern warplane. A bomber without gun turrets was suicidal. The concept violated everything the RAF had learned about survival in the air war.
De Havilland went back to Hatfield and built it anyway.
On November 25, 1940, his son Geoffrey Jr. lifted the prototype off the runway at Hatfield. In comparative trials it was faster than the Spitfire. Faster than the Hurricane. Faster than anything the Luftwaffe could send to intercept it.
The de Havilland Mosquito — the Wooden Wonder — went on to become the most versatile combat aircraft of the Second World War. Forty-three variants. 7,781 built. The lowest loss rate of any aircraft in Bomber Command. It breached prison walls at Amiens to free French Resistance prisoners. It destroyed the Gestapo's Copenhagen headquarters. It flew unarmed over Berlin and came home.
Hermann Goering told his aircraft industry that it made him furious. He turned green and yellow with envy, he said, that the British had knocked together a wooden aircraft while Germany could not match it.
But the story behind the Mosquito is also the story of what it cost. Geoffrey de Havilland lost his son John in a mid-air collision in 1943. He lost Geoffrey Jr. in 1946, pushing the sound barrier in an experimental jet. He lost his wife the year after that. He kept working through all of it.
Then came the Comet — the world's first commercial jet airliner — and the disasters of 1954 that grounded it forever. And the lesson those disasters taught every aircraft designer who came after.
This is the full story of Geoffrey de Havilland.
