Whyld says a self-build drone suitable for journalism could cost "below a thousand pounds, plus about £350 to stick a GoPro camera on the front of it" – news that will please media organisations that are short of funds.

But he says there's two approaches to making drones: "The BBC has quite a big budget with three of these machines and I'm just building stuff in my front room."

"People that don't know what they're doing are drawn into spending lots of money. You can get a Hollywood-standard system by buying cheaper equipment and building it up and knowing the components. Otherwise you can spend thousands and thousands – and if you crash it's all gone."
