i dont think its amazing thing ... a man can pull it so can a suv ...
no tires cannot explode on 20/mph .. velocity of a stationary plane is at max as accelerion is zero .. moving it is the most tricky and dangerous thing because acceleration is inversly proportional to velocity. when the plane moves ... acceleration required is lesser than the velocity of the plane, so its easier for the car..
person who towed the plane... he worked for several minutes to just slightly move the plane. when it moved, increasing speed of a moving plane is eaisier than moving a statinary plane.
please note that truck which moves a plane has lesser power than this car ...
