No plasma-propelled aircraft has successfully taken flight on Earth. Such designs have found some success in space, where gravity and drag are minimal, but a vehicle hoping to fly within Earth’s atmosphere will need at least an order of magnitude more thrust, Roy said.
Also, the power source needs to be extremely lightweight yet still produce enough power to generate the necessary plasma. Not to mention the fact that the very same plasma that will allow the aircraft to fly also will interfere with electromagnetic waves necessary for communication with the vehicle.
