1. A method comprising:

  • determining, by a computing system, a variable deployment-rate profile for deployment of a payload from an unmanned aerial vehicle (UAV), wherein a line couples the payload to the UAV;

    the computing system causing a line-deployment mechanism to operate according to the determined variable deployment-rate profile to lower the payload towards the ground, wherein the variable deployment-rate profile is such that the deployment rate of the line varies while the payload is being lowered to the ground;

    detecting, by the computing system, at least one release indication that indicates that the payload is at or near to the ground; and

    in response to detecting the at least one release indication, the computing system causing the payload to be released from the line.
