U.K. T.V. Prog: Seaside Rescue, Helo Question.
As a groungripping life-long aviation enthusiast, may I ask a question on this forum, please?
In the BBC Tv. Prog., Seaside Rescue, in several episodes, when the crewman is just starting to descend on the hook from the doorway of the helicopter, he appears to remove a pin or something from the hook/winch mechanism, and show it to the guy operating the winch.
Can anyone tell me what this is, and how/what it is used for , etc?
Thanks. N.Z.
