China has flown a 10-ton electric passenger plane with a pilot on board for the first time, after months of autonomous flights. The aircraft is designed to carry 19 passengers between cities at 300 km/h, with a range of up to 400 km. After its first unmanned flight in February, it completed 19 autonomous test flights. The plane is not yet certified, and its range remains limited for commercial routes. China is testing an electric aircraft that can fly with or without a pilot.
