Pic of an MSP landing on KK DZ. Brian should enjoy this. You can see the TROC (transfer release operating cable) whipping in the airflow. This cable triggered the pull of the main parachutes from the aft face of the platform to the top of the load so it could descend in a horizontal manner. It was crude but it (usually) worked. Other transfer methods were tried, like the one that had a form of railway points system, but they all had drawbacks.
After the drop it was reeled in the the ALM and stowed at FS245.
This is a lead in to an airdrop tale which I will relate next time, but which may make dragartist spill his holiday cocktail !
