The day after a laser in the sky caused a Virgin plane to return to Heathrow, there has been a call by Iata for drones flown by the general public to be regulated. The stories are linked not just because they both relate to air activity but because they relate to the use of technology for entertainment rebounding. We have become so used to technology that it can be difficult to realise the implications of its abuse. The problem is will increased regulation fetter innovation or stimulate the development of additional technology - sensors, for example, that force a drone to move away from aircraft?
