Idiotisch: Kontrollverlust über Phantom 4. Der Copter kehrt sofort zurück - aber die Fersehturm-Kugel ist im Weg :-)

if you wanna see how the anti-crash-sensor of the phantom 4 works in real life.. early in the morning, almost no one on the street. this was a spontaneous flight with a very unexpected end.
the anti-crash sensor of the phantom prevented the copter from crashing into the tower.
