whoever maintained the power lines would have made an insurance claim against the airline to repair the damage. The insurers would have insisted on full details of the damage and costs of repairs down to the last penny
Let's say I'm the power company and your plane just brought down three wires between two towers a hundred feet apart. I don't trust the integrity of the downed lines in such cases, so I'm going to replace them all. I'm going to bill you for 300 feet of wire, for the splices needed to attach it at the towers, for the payroll to cover it, for the recovery costs of the downed line that I'm sending to recycle, and for any strain damage and repair parts on the towers themselves.
The one thing that I don't care at all about is where in the line the wires were severed. I'm assuming you didn't run off with a length of it wrapped around your plane. To me it's six hunks of random length wire that are going to be lying on the ground to be spooled onto the salvage truck.
