1. An aerial delivery system for aerial delivery of cargo from an aircraft, the cargo being provided on an aerial delivery platform, the aerial delivery system comprising:
an extraction assembly for transmitting to the platform a drag force generated by an extraction parachute, the extraction assembly comprising:
a coupling arrangement configured to couple a main parachute deployment line to the extraction parachute, the coupling arrangement being switchable from an open configuration in which the main parachute deployment line is uncoupled from the extraction parachute to a closed configuration in which the main parachute deployment line is coupled to the extraction parachute;
a coupling device configured to switch the coupling arrangement from the open configuration to the closed configuration in response to the platform moving to a first predetermined position relative to the aircraft; and
an extraction parachute release device configured to uncouple the extraction parachute from the platform;
wherein the aerial delivery system comprises an extraction parachute release assembly arranged to cause the extraction parachute release device to uncouple the extraction parachute from the platform in response to the platform moving to a second predetermined position relative to the aircraft; and
wherein the second predetermined position is a position reached by the platform after the platform has passed the first predetermined position.
