There’s a company that wants to install electric motors into airplanes (so they don’t need tug vehicles). Here is the successful installation and test of the first in-wheel WheelTug system in Prague on a 737-700. During testing, pilots were able to push the plane back, and taxi without waiting for a tug or powering up the engines. Pilots were able to move the plane through motors in the nose wheel powered solely by the aircraft’s APU.
