I sent a pic of this exposed cable on our 757-200(OW) to Mrs. RW last evening before we departed so that she had some evidence for the personal injury attorneys. Somehow we missed all of the mountains and water and made a safe landing. I did tell the FA about it when we were leaving and he said that it had already been reported. When I told him that I tugged at it a bit and that when it sparked I stopped, he paused but then got the joke.
