Fold up wings is a must, plan B would be to find an airport, plan C is to just ferry fuel back and forth by hand. While I like the idea of a 100% electric plane I sadly don't thing that is viable at this time. (Batteries will weigh to much.) That said a hybrid plane may actually make some sense. One where the turbo gets used as an APU, so two electric motors and two gas motors. In a long haul the gas motors would be dialed back then the electric motors will take up the slack, the Turbo apu will both supply power to the plane while also recharging the batteries on short flights. Entirely spit balling there just a off cuff idea....
