In 1936, the invention of helium-filled airships garnered criticism due to multiple accidents, most notably the Hindenburg disaster in 1937. This event underscored the dangers of airships using flammable gases, prompting public backlash and diminishing confidence in their safety. As a result, the use of lighter-than-air crafts for passenger travel rapidly declined. The incident spurred the development of safer aviation technologies, ultimately leading to the predominance of fixed-wing aircraft.
