News about advances in electric cars is an everyday occurrence. Talking about electric airplanes, however, is almost like science fiction. Until now. A Swedish startup, Heart Aerospace (https://heartaerospace.com/) is preparing to put the first fully electric commercial passenger airplanes into service as early as 2026. United Airlines has given this project the final green light by ordering 100 units of the first model to roll off the Swedish company’s production line. It is a 19-passenger aircraft designed for short-haul routes. In addition to the order for these aircraft, the airline’s investment fund, United Airlines Ventures—launched last June—will invest in Heart Aerospace, alongside Breakthrough Energy Ventures, a fund led by Bill Gates, and the Arizona-based regional airline Mesa Airlines, which has also ordered aircraft from Heart Aerospace.
