A method for landing a flying object at a point location comprising:
- (a) flying a flying object substantially horizontally towards a retrieval apparatus including a cable and winch mounted on the location,
- (b) releasing from the flying object a trailing cable or pole carrying at its end a hooking up device,
- (c) causing said hooking up device to engage the cable of the retrieval apparatus,
- (d) continuing the flight of the flying object and causing the winch to unwind the cable during the continuing flight,
