It's hard not to get caught up in the romance of delivery drones, especially when start-ups keep producing spiffy promotional videos set in a fantastical land of airborne courier services. But underneath all this hoopla, progress is certainly being made.

London-based company has begun trials of its autonomous drone delivery service, claiming it is capable of shipping small objects at the touch of a smartphone button. The team has engineered its drones over a number of years at London's TechCity.
