- GE Aerospace, NASA, BETA Technologies, and Boeing achieved the first hybrid electric flight above 30,000 feet, matching commercial aircraft altitudes.
- The flight test, part of NASA's EPFD project, used a modified Saab 340B with a megawatt-class hybrid electric propulsion system.
- Hybrid electric systems combine electric powertrains with gas turbines for improved efficiency and fuel flexibility, targeting over 20% better fuel burn.
- Public demonstrations are planned at the Farnborough International Airshow, showcasing the aircraft in flight and static displays.
- Previous milestones include ground tests in 2016, altitude tests in 2022, and system integration achievements by 2026.
