Volta Volaré has begun taking orders for its four-seater GT4 hybrid private aircraft it calls "the most technologically advanced private aircraft available anywhere on Earth." Though the GT4 is perfectly capable of taking off and flying powered only electrically, a gas engine starts when the airplane's battery drops to 25 percent capacity in order to recharge it mid-flight. Surprisingly, perhaps, Volta Volaré makes a strong economic case for the GT4.
