Evalu8ter - I take your point but even if the mass of the Chinook or the rotors snap the wires, what about the damage done to the airframe, rotors or crew? Seems a very optimistic attitude to say 'let them break wires'.
From the looks of the damage on the pic, the wires have a good account of themselves, the wokka straining against their restraint then finally being let forth with an almighty twang.
A frightening, nee shocking, experience for the crew no doubt. Isn't it standard procedure to refer the pilot as Sparky from now on?
