We are building a family of commercial hybrid-to-electric aircraft with unmatched economics over short-haul (to 1,500 miles), addressing 80% of departures and 50% of aviation emissions today. Our quiet range-optimized propulsion technologies are power source-agnostic, offering carriers an optimal journey to zero emissions across batteries, fuel cells, turbines and synthetic fuels. Our vision is to develop zero-emissions air networks to bring fast and affordable travel to every community. Our planned family of aircraft include business or commuters (ZA10), regionals (ZA50), and single-aisles (ZA100), as well as vertical lift, light attack, and tactical airlift platforms for the military.
