The most insane DJI Phantom 2 fly away, crazy, out of control!

My nightmare flight with my DJI Phantom 2 and GoPro Hero 3+ Black Edition. I realize now that the calibration i did right before takeoff must have been done nearby something very powerful that really messed up my system. I have never experienced such horrific behavior from my Phantom 2 ever before...! I am so happy no one were harmed by this crazy flying lunitic :-)
This happened in Stokmarknes, Vesterålen, in north of Norway.
