Heart Aerospace flies largest electric plane

Heart Aerospace completed the first flight of its X1, the largest battery-electric aircraft ever flown, on August 12, 2026.

Heart Aerospace has completed the first flight of its X1 demonstrator aircraft. The company states this is the largest battery-electric plane ever to take to the skies.

The piloted flight occurred on August 12, 2026, at Plattsburgh International Airport in New York. The mission lasted 27 minutes.

The aircraft has a wingspan of 106 feet and a length of 76 feet. It weighed more than 25,000 pounds at takeoff. During the flight, it climbed to 1,100 feet above ground level. Its electric propulsion system delivered more than one megawatt of power. The flight was conducted under an FAA Special Airworthiness Certificate.

Heart designed the mission to prove all-electric flight can work at a scale relevant for airlines. Powered only by batteries, the X1 used about five dollars' worth of electricity for the flight.

Why the milestone matters

The flight took place as global jet fuel prices remained high. Prices averaged $3.50 per gallon in early August 2026. This was up 63 percent from the previous year. Electric propulsion could cut operating costs and reduce airline exposure to oil market volatility.

Anders Forslund, founder and CEO of Heart Aerospace, said the flight demonstrated electric flight at the scale of a commercial airliner. He stated electric commercial aircraft have the potential to reshape airline economics and lower the cost of air travel. Forslund said this vision includes more affordable, frequent, and cleaner air service.

Path to the

ES-30 airliner

The X1 is a full-scale demonstrator for Heart's planned ES-30 production aircraft. The company is using it to validate key technologies, aerodynamics, and flight performance.

The ES-30 is a conventional fixed-wing, 30-seat hybrid-electric regional airliner. Heart is developing it for FAA Part 25 certification. Major carriers including United Airlines, Air Canada, and JSX have already made customer commitments.

United Airlines CFO Michael Leskinen called the X1 flight a major technical achievement. He said United has been proud to support Heart Aerospace. Leskinen added that electric commercial aircraft have real potential to deliver a better travel experience while strengthening the business.

Air Canada's John Di Bert, executive vice-president and chief financial officer, noted the energy transition in aviation will need many solutions. He said the airline's investment in Heart reflects a commitment to transformative technologies.

Lower costs ahead

Heart targets entry into service for the ES-30 in 2031. The company expects the aircraft to cut operating costs by more than 40 percent compared with today's regional jets.

Savings would come from lower energy costs, simpler electric propulsion systems requiring less maintenance, and higher reliability from integrated electronics and software design. Further gains could come from improving battery technology and limiting exposure to future emissions-related fees.

Ben Stabler, Heart's chief technology officer, said the X1 program has given the company full-stack capability. He stated this capability is being carried directly into the ES-30, which he called the foundation of a broader technology platform for electric airliners.

Heart is already building the first pre-production ES-30 at its pilot plant in Los Angeles. Flight testing of that aircraft is scheduled to begin in 2028.
