The drone crashed into a lake while it was transporting blood samples from a hospital to a laboratory.

It is highly probable that a short circuit occurred during the flight of the drone in a plug-in connection, which resulted in a failure of the 5 volt supply of the GPS receiver and other components. For this reason, the drone could no longer determine its own position and initiated an emergency landing according to the internal logic of the Flight Termination System (FTS). This took place, as planned, by switching off the four engines and expelling the emergency parachute.
Meteorological conditions or other external circumstances could be ruled out as the cause of the emergency landing.
