Once you lift off the ground you have stored energy. My solution is outside the box, but the only one I can think off that does not defy the laws of physics. Leave the craft, unmoved, on the tarmac. Have David Copperfield make it disappear then reappear. Assuming the temperature remains constant so the tires do not inflate or deflate somewhat there is zero stored/kinetic energy. Voila, the miracle on the tarmac :-)
