The plane (jet or screw) stands on a runway. The runway has a mobile covering (such as the tape conveyor). This mobile covering can move against a direction of plane running. Also, the
covering has a control system which arranges speed of cloth movement so that wheels rotation speed of the plane was equal to speed of cloth movement . A question: whether the plane on this cloth can run up and take off?
