Worked on Horse Sands Fort a good many years ago. We had the JAT team and a Chinook for a day of lifting equipment on and off, and have fond memories of 100 MPH dried Pigeon Guano hitting me in the face like hail stones. Was good fun having the tails of guide ropes whipping around in the wind and tying themselfs around the legs as the Chinook lifted the load
Was amazed to see my Cabin still on the West side of the Fort, I thought this Fort had reverted back to the Army.
The hook these people used was a fibreglass pole/hook with a metal core, this had a wire cable comming out the base and just dangled on the floor.
