The De Havilland Comet was the world's first commercial jet airliner, introduced in the early 1950s. It was designed to provide faster and more comfortable air travel, featuring a sleek design and advanced technology for its time. The Comet could carry around 36 passengers and had a cruising speed of approximately 450 miles per hour. Despite its innovative design, the Comet faced serious safety issues, leading to several tragic accidents. Investigations revealed structural failures due to metal fatigue, prompting significant changes in aircraft design and safety regulations. The Comet's legacy ultimately paved the way for future commercial jets, influencing the aviation industry for decades.
