Summary
May 20 marked the first hybrid-electric flight above 30,000 ft for GE Aerospace’s modified Saab 340B, a commercial-altitude milestone for megawatt-class electric propulsion.
The testbed pairs a hybrid-electric engine in the right nacelle with a standard GE CT7 turboprop on the left, and GE said the system motored and generated at full power while sustaining altitude for two hours.
Beta Technologies integrated the system and ferried the aircraft from New York to Farnborough via Canada, Greenland, Iceland and Scotland, using hybrid-electric mode on every leg.
NASA’s Electrified Powertrain Flight Demonstration program, with Boeing and Beta, underpinned the effort after 2022 ground tests simulated operations at 45,000 ft.
GE said the flight data will guide future hybrid systems and feed into its RISE/Open Fan work with Safran, helping define battery, thermal-management and power needs for larger aircraft.

Overview
On July 20, 2026, the aviation industry reached a major milestone with the first high-altitude hybrid-electric flight, soaring above 30,000 feet. This achievement, celebrated by GE Aerospace’s CEO as historic, marks a significant leap in sustainable aviation technology. The flight was made possible through a collaborative effort, with Beta Technologies playing a key role. It showcased a megawatt-class hybrid-electric propulsion powertrain developed by GE Aerospace, which combines advanced electric motors, a gas turbine, and energy storage. The successful demonstration at commercial altitudes proves the viability of hybrid-electric systems for everyday aircraft, paving the way for greener air travel.
