de Havilland Ghost 50 at RAF Museum Cosford. The Ghost originated when de Havilland started work on what was to become the Comet in 1943. Frank Halford's first design, the H-1, was just entering production and he was able to meet the power requirements of the Comet by scaling up the H-1.
Powered by four de Havilland Ghost jet engines, the Comet could reach speeds of 500 miles per hour (halving journey times around the world), and fly at an altitude of 40,000 feet, a performance previously the preserve of military jet fighters. Twenty months after the launch, there were 17 Comets in service.
