Drones are real expensive Unmanned Aerial Vehicles or remotely piloted aircraft whose fight is either managed by the computer or by a remote control by a person following it on the ground. It might seem expensive to us and we might feel the pinch when we buy an expensive car, an engagement ring, a boat or a house.
But the satisfaction is that we at least are physically using the items and deriving pleasure out of them. So it pays off for the huge expense incurred. But just imagine how it feels for a scientist who pays millions of dollars for purchasing the drones and it fails to achieve the target after it is launched and splashes into an ocean or drops onto an unknown planet. Following are the most expensive drones ever launched.
