I just don't understand some of these crashes. I have had my P4Pro for well over a year now and have flown next to all kinds of steel structures with never an issue. I've flown it the length of a steel bridge (inside the framework) many times. Along high powered hydro lines. Right up close to the hub of some huge wind turbines and even followed alongside a freight train this spring and not a single problem.
I guess I just got a great DJI Pro 4, an excellent iPad Mini 4, a top notch controller, great propellers and super duper batteries. I'm just a lucky guy I guess.
