Drones, also known as unmanned aerial vehicles (UAVs), have been one of the main talking points at this year's Farnborough Airshow.

Better known for their military uses, they are now being developed for many civilian applications, from farm management to border control.

And smaller drones, programmable by laptop, are even within the price of the hobbyist, retailing for a few hundred pounds.

Craig Lippett, who trains people how to use drones for the firm Resource UAS, showed off a drone with folds up, developed by Danish firm Sky-Watch - though it costs £35,000 ($54,300).
