I have written about drones before, and there are undoubtedly privacy and security concerns.   I did not realise however how sophisticated drones had already become, because it is one thing to read about it and it is another thing to watch a drone rise 200 metres above your head, and then fly half a kilometre in 10 or 15 seconds, before returning to you.  The drones I have played with were far inferior to one that a friend recently showed me.  He bought it in America, and it is one of the R50 000,00 type drones, so it is relatively simple compared to what the American military will have, but extremely fast, high-powered and with a range of 2 km.  It is quite noisy as well, and when it is flying around a house and a golf course, it can take HD pictures in 4k quality – allowing you to really see things that your neighbours might not want you to see for example.  

I think we are going to see legislation about these quite soon, and I just cannot see that companies will be able to use them to fly goods to you as Amazon once suggested.  It may be possible in more rural areas, but with planes taking off at a nearby airport, and drones flying at heights that aeroplanes and helicopters can fly at, one can see potential for disaster.  The commercial uses are certainly going to include, as they already do, real estate and I have seen quite a few wedding videos and photographs notably showing the chapel, etc and the guests from the sky, which are also quite dramatic.  Height can give you a completely different perspective on a property that you may know well, and golf courses are also beginning to use this to promote themselves. Any property or estate that has a lot of natural greenery will generally look spectacular from the sky and there is no doubt that it is going to be used much more in all sports events, from overhead shots in horseracing to stadium shots in any sport where you can now go closer than you would in a helicopter.
