The Engineering Error That Killed 99 Passengers

This plane kept on crashing, it took 3 crashes and 99 lives to finally have it grounded and thoroughly investigated. The investigation revealed a very import engineering law. The de Havilland Comet crashes shone light on the importance of considering fatigue when it comes to structural components that undergo repeated loading and unloading. As a consequence of the failures, the Paris-Erdogan Law was discovered which is widely used today. Without the de Havilland Comet, our understanding of fatigue and fracture would not be at the level that it is today.
