Scientists of the Massachusetts Institute of Technology, USA, managed to fly a small plane with the help of ion i.e. current or atomic molecules. After this success, the hopes of making big aircraft without engines and non-fueled airplanes have been tied up after the initial model of the American Massachusetts Institute of Technology scientists tested successful. This aircraft was released from a ramp using the principle of the catapult. It was only a short distance in the first place and it started falling down on the ground. After such many efforts, it seemed to float in the air like any common plane. The biggest feature of this flight was that there was no engine in the aircraft, no fuel was used.
