The Swiss postal service has begun testing parcel deliveries by unmanned drones.
Eventually for areas which are difficult to access such as mountanous regions this will be the postal service of the future.
Extensive tests will analyse the technical restrictions of the drones, including limited battery life.
Swiss Post says it envisages using the drones for mainly emergency situations, which could involve bringing supplies to an area that has been cut off from the outside world following a storm.
Tests are going to run until the end of July although widespread use the flying postmen is not expected for another five years.
