The tail end of 2015 will see thousands of new recreational drones being unwrapped in front of the Christmas tree, mostly tiny but some larger, and a lot of them will carry cameras. Expect the skies to be thick with the little creatures on Boxing Day as users start to master their radio controllers, and expect many tears to be shed as their craft crash into trees, smash into overhead cables, or fly off out of control towards the local fishing pond. Hopefully no dog walkers will be injured.
