There is one major advantage the helicopter has that a plane does not – that is, the ability to simply hover around in place, turning 360 degrees in a horizontal plane and take off in that direction after that, but the price to pay would be sacrificing its speed. How about a hovering airplane. That sounds like an amalgamation that hails from the future, but it could very well arrive sooner than we expect.
