| Mr Hesselink, a senior research and development manager at the Netherlands Aerospace Centre, says growing demand for drone delivery services will call for "a network of drones". | |
| While small drones will be used to deliver goods direct to your home, larger drone aircraft will be needed to carry goods to out-of-town distribution centres, he argues. | While small drones will be used to deliver goods direct to your home, larger drone aircraft will be needed to carry goods to out-of-town distribution centres, he argues. |
| These larger drones would be of a fixed-wing design like aeroplanes, rather than the quadcopter design favoured by hobbyists. These are more fuel efficient, fly for longer and can carry more cargo. | These larger drones would be of a fixed-wing design like aeroplanes, rather than the quadcopter design favoured by hobbyists.

| Drones are subject to less stringent safety rules than piloted aircraft carrying passengers. This may get round some of the safety fears raised about using circular runways, including the risk of aborted take-offs or landings. | Drones are subject to less stringent safety rules than piloted aircraft carrying passengers.
