Aircraft with Hybrid-Electric Propulsion Reached an Altitude of Nearly 9,200 meters (30,000 Feet)

Source Summary

GE Aerospace, NASA, Beta Technologies, and Boeing successfully demonstrated the feasibility of electrified aircraft engine systems. An aircraft with hybrid-electric propulsion reached an altitude of 30,000 feet, or 9,144 meters. This is the same cruising altitude achieved by kerosene-powered passenger planes. During the tests, the team's longest flight duration in hybrid-electric mode exceeded two hours.
