Air Traffic Management and Unmanned Aircraft Bill [HL]

My Lords, there is a remarkable similarity between the discussions on this amendment and the discussions we have had over the years on self-driving, autonomous cars. The only difference is that this is three-dimensional and the other one is generally two. The noble and gallant Lord, Lord Craig, and the noble Lord, Lord Glenarthur, both gave examples of a question I have long had. The noble Lord, Lord Glenarthur, mentioned two drones meeting over a pipeline or something, but the problem remains: how does a constable identify the person who is in control, or whatever? He is sitting in his car with his machine—or however he is going to do it—but how will he identify that? He cannot really arrest either the drone or the person unless he can identify them first. I hope that the noble Baroness will be able to explain this rather simple bit of logic which has escaped me so far.
