In the late 1950’s, intercity air travel was on the rise. But while a trip from New York to Boston by airplane might only take about an hour, you’d still need to get to and from the airport. And in many congested cities, that was already taking longer than the flight itself. As a solution, helicopter airlines had begun to crop up in major cities, letting passengers skip over traffic to connect airports with their city centers. But helicopters were ultimately too inefficient to become a viable form of mass transport. The Rotodyne was going to change all that. Taking off from downtown rooftops and heliports, but flying faster, further, and more economically than any helicopter, the Rotodyne would be the quickest way to move from one city centre to the next.
