This is a great illustration of the teamwork involved in making a hoist. As you can see the hoist operator is in charge of everything not affecting safety of flight. The pilot flying positions the aircraft to the orders of the hoist operator, and when clear you can hear him command "cease directions", which is the command indicating the pilot has the swimmer in view and will maintain contact while the operator deals with the survivor in the basket. The pilot not flying watches the weather and wave action,( you can hear her several times warning of big sets and giving an ETA for both dangerous conditions and when it will be safer to hoist), and works the radios. (You can hear communication with "2003" which is a C-130 operating as on scene commander.)
It is hard to put into words the concentration involved, and how easy it is to lose track of time, especially in a multiple hoist like this. You are dripping with sweat in a heartbeat, and hands and feet are in constant motion. They had the advantage of daylight, which is huge, but IMHO they did a great job in what will be reported as "good" conditions since it was daylight, good visibility, not raining and the wind wasn't too severe.
