The Astro Jets was an off-the-shelf rotojet ride manufactured by Casper claws in West Germany that opened on March 24, 1956 in Disneyland's Tomorrowland. Due to a conflict with United Airlines, the official Airline of Disneyland, the attraction's name was changed to the Tomorrowland Jets. American Airlines had begun calling its new Boeing 707 jet airliners Astro Jets. The Tomorrowland Jets closed September 5, 1966. As part of the new Tomorrowland the name was changed to Rocket Jets and built on top of the People Mover loading station to save space.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
