About this model

This is for the MAMSS x McGill competition and I am from McGill University! These three engineering disasters are known by every mechanical engineer. Textbooks and professors mention them incessantly (and with good reason), as they provide extremely important lessons that all mechanical engineers must remember. The de Havilland Comet disasters resulted in large tears in the plane's fuselage during flight on 26 occasions. 13 of those occasions were fatal, and contributed to 426 fatalities. The comet was at the forefront of jet propulsion technology, and was flying at a much greater height than most aircraft of the time. Ultimately, its square windows were the root of its downfall. The sharp corners on the windows created stress concentrations in the fuselage, and paired with the repetitiv…
