We've had a few scratchy heads around here trying to work out what sort of power lines they could have been. The spacing of the dents on the wing don't appear to match up with any known cable spacing. Must have been at a funny angle....
Talking of banana jets, there was a flight of four in Turkey I think (mid 80's) flying down a valley when they came across cables strung across the valley. From what I was told, 1 went over, 2 and 3 went under, and 4 went through! Got back safe with no refueling probe or canopy and a white face navigator (the cable apparently had gone up the nose, up the windscreen, through the canopy and hit the blast shield in front of the Nav).
