Wow! With such ingenuity & trial and fixing errors, it is not surprising how the US army, these days, can set up a whole base, complete with toiletry, bathing& operational kitchens in a couple of days: all done in virgin bushland. The thought, design & construction is so thorough. It doesn't show the clearing of tracks for the running of cables so I guess they used cane knives=a job in itself.
I had wondered how the setup prevented the prop from fouling the cables but it was worth watchingthe whole film to see how it was done: a forerunner of aircraft carrier tech I presume.

Cheers
