A company has successfully flown its battery-electric aircraft for 27 minutes on just $5 worth of power, the world's largest such plane. US-based Heart Aerospace, originally founded in Sweden, weighs 11 tonnes and took off from Plattsburgh International Airport in New York on August 12. The X1 demonstrator reached a height of 1,100 feet on an all-battery-electric propulsion system producing more than 1 MW. It has a 106 ft wingspan, four electric motors, and can seat 30 passengers. It is only a test aircraft planned for Heart's ES-30 regional plane.
The X1 tests the technologies, systems and manufacturing processes for the final aircraft. ES-30 will be hybrid-electric instead of relying only on electricity. The ES-30 will have an all-electric range of 200 km and an 800 km hybrid-electric range. The plane can charge fully within 30 minutes.
The $5 cost of X1
The flight had several other operating costs, such as pilots, maintenance, airport charges, battery depreciation/replacement, aircraft financing, insurance, etc. The $5 is only the cost it incurred for the electricity used for the 27-minute flight.

Timeline of the electric-hybrid aircraft
Heart Aerospace started developing the electric regional aircraft in 2019 after entering the Y Combinator's W19 programme. Within a year, it showcased its early ES-19 concept, drawing interest from various parties. It raised $35 million in 2021, with investment from United Airlines and Mesa Air Group. Its first subscale flight took off in December 2021 to validate the electric propulsion. It unveiled its 30-seat ES-30 in September 2022, and then raised another $107 million to develop the X1 demonstrator.
It developed the X1 within two years and started ground testing in October 2024. The company established the X1 flight-test base at Plattsburgh, New York in January 2025. It plans to test the pre-production ES-30/X2 programme in 2028 and is targeting 2031 for ES-30 to enter service.
