The Sirius Jet will fly up to 1,150 miles (1,851 km) at speeds up to 323 mph (520 km/h) on a clean liquid-hydrogen powertrain. It'll rise vertically off a pad thanks to a deflected vectored thrust system using 20 smallish electric ducted fans.

It's the work of Swiss startup Sirius Aviation AG, which has apparently had a "team of 100+ engineers" beavering away at "intense R&D" on this project in the insanely picturesque lakeside town of Baar since 2021. Sirius says it's already started the certification process with the FAA, with a demonstration plane scheduled for first flights in 2025. Full certification, commercial deliveries and shuttle flights are planned for 2028.
