Flying for the first time in 1949 - a full eight years before the Boeing 707 - the Comet was indeed a revolutionary aircraft. Not only was it the world's first jet airliner, it would cruise at altitudes far higher than other commercial airliners of the time: the DC-4 flew at an altitude of 22,000 ft, against the Comet's 40,000 ft; the Comet would cruise at almost 500 mph compared to the "rival" DC-4's 265 mph.
The de Havilland pioneers had a host of "firsts" to tackle in the design of the new aircraft, not least of which was pressurisation at higher altitudes than airliners had ever flown before. After exhaustive testing, the Comet entered...
