The De Havilland Comet was one of the first commercial airliners ever designed. As with any designs which explore previously uncharted regions of invention, the Comet went through several stages of flaw. Throughout the existence and development of the Comet as a commercial airliner it suffered many crashes and equally as many design changes. At the time of it’s design, the Comet redefined the possibilities of air travel. It attempted to safely transport it’s passengers at speeds and altitudes never reached before. The Comet pushed speeds of 800 km/h and altitudes of 10,000 m . The repeated failure in the design of the comet was not due to one specific engineering failure. Over the history of the Comet, failure in many areas prompted the designers to re-evaluate the plane. Due to the fact that the complex engineering area of aerospace design were at the time just beginning to develop, it seemed that as soon as one flaw with the plane was solved, another plane went down in flames, leaving the designers "back at the drawing board".
