The world's largest all-electric plane has successfully completed a test flight, the first step in a long process its developers say will led to an era of low-cost, pollution-free air travel.
Seattle-based electric motor manufacturer Magnix teamed with local airline Harbour Air to retrofit a Cessna Grand Caravan 208 with a 750-horesepower zero-emissions motor and conducted its first test over Moses Lake, Washington, Thursday. The 37-foot Caravan is one of the most popular medium-range commuter airliners in the world. It can carry up to nine passengers.
