Are they safe? Delivery drones will fall rapidly out of favour it they fall rapidly from the sky after running out of juice or crashing.

In October, West Midlands Police reported a defect in its DJI Matrice 200 surveillance drone to the UK's Civil Aviation Authority. The drone experienced a sudden loss of power even when it had battery charge remaining.

"The biggest challenge is to reduce the risk of collisions between drones and other aircraft," says Mr Morier.

Wing says it has performed "tens of thousands of test flights" in the US and Australia, and is heading to Finland next year.

Its drones use "redundant motors, batteries and navigation systems with intelligent controls, so back-up systems can help keep aircraft safely in flight", the company says.

But Beyond Visual Line of Sight (BVLOS) flights - where drones travel autonomously or are controlled by pilots remotely - are only likely to become viable once "detect and avoid" technology has been approved by regulators.

"Nasa has successfully built and flown a system this year," the US Federal Aviation Administration (FAA) says. "But no 'detect and avoid' systems have received approval as yet."

It's a point reiterated by European regulators.

"There is no 'detect and avoid' technology capable of ensuring [that drones don't collide with other aircraft] at the moment," says Mr Morier.

For this reason it has stipulated that non-commercial drones cannot fly above 120m (394ft), although who polices this is another issue.
