"The aircraft would take off vertically like a space shuttle, and — once it would climb to more than 100,000 feet — ramjets, normally seen on missiles, would blast off to help the plane reach its super speed.
“When the vehicle has reached supersonic speed at very high altitude … the trajectory is gradually curved until it becomes horizontal,” reads the patent.
A video from patent-explaining website PatentYogi gives an overview of the proposed aircraft. Passengers on the plane would recline in hammocks, remaining comfortable for what the site calls a “rollercoaster” of a flight"
