World's largest electric aircraft flies on $5 of electricity

Heart Aerospace says its X1 demonstrator—described as the world’s largest electric aircraft—flew for 27 minutes on Wednesday using about $5 worth of electricity. The company flew the aircraft from Plattsburgh International Airport in upstate New York on August 12, after closing its Gothenburg operation and moving the program to Los Angeles. During the test, the aircraft taxied, took off, climbed, maneuvered and landed, reaching 335 meters while producing more than one megawatt via all-electric propulsion. Heart stresses the $5 figure reflects energy for the demo flight, not full operating costs. The X1 is tied to the ES-30, a hybrid-electric 30-seat airliner aimed for first pre-production progress in Los Angeles, flight testing in 2028, FAA Part 25 certification, and entry into service in 2031.
