I measured the 3D object in Google Earth and the big one on the main street is 30 meters tall from the ground. I assume the smaller pylons carrying your three wires are no taller (they don't even show up in 3D on Google Earth which suggests they are actually smaller). The distance between pylons carrying those wires is quite large -- 200 meters -- and you are 100 meters away. Seeing the cable will be drooping to it's lowest point at your crash site, it is quite feasible that it was hanging at 20m.
The altitude between takeoff and crash was pretty level, yet you show negative altitudes (-2.6m) during the flight. Did you take off higher than street level? Your takeoff point was recorded at 0m. You were up around 16-17m at the time of loss of control, add 3m error in takeoff altitude and you get close to 20m from ground level. That's awfully close to where the wires are. If you were flying FPV by looking at your device in order to frame the camera for shooting your pictures, and not looking directly line of sight at the aircraft, as well as not having full situational awareness of hazards around you, it would explain how that came about. It is easy to get swept up in what the camera sees, forgetting to check the environment around the aircraft.
Sorry for your crash but it could have been worse. Other RC aircraft colliding with power lines have resulted in a large spark and flames, with nothing left to salvage. Not to mention the blackout and damage to the power grid which you would have to pay for if they determine the cause of the accident. |
