Congrats to @AndersForslund1 and @heartaerospace (W19) on the first flight of X1! It's the largest battery-electric aircraft ever flown, with a 106-foot wingspan and a takeoff weight over 25,000 pounds. The entire 27-minute flight ran on about $5 worth of electricity. Next comes the ES-30, their 30-seat hybrid-electric airliner targeting service in 2031.
