ALL the thrills of a looping airplane are available in a new amusement device which recently made its appearance in Los Angeles.
A car resembling the cockpit of a plane is supported on a hollow steel tube which pivots on a large ball bearing mechanism at the top of its steel frame.
The device is powered by a small electric motor which swings the car back and forth, gradually increasing the arc until enough momentum is developed to carry it over the top.
