In the US, a remarkable incident occurred last year involving an Amazon Prime Air package delivery drone. During a test flight in the summer of 2021, a test aircraft crashed into a field in the US state of Oregon. Overheating due to a short-circuit in the batteries subsequently led to a large wildfire, in which the drone also went up in flames.

The incident took place in June 2021, according to a report by the American aviation authority FAA. The prototype delivery drone type MK27 was flying at an altitude of 160 feet (approx. 50 metres) during a test flight when an engine failure led to acute problems resulting in a crash.

The investigation into the crash shows that the aircraft made an uncontrolled dive to the ground. Once on the ground, the aircraft's lithium-polymer (LiPo) battery caught fire. This subsequently led to a wildfire, in which several hectares of a field went up in flames.

It is remarkable that the incident in June is not an isolated one. A few weeks earlier, the same Amazon prototype delivery drone, weighing 40 kg, also fell from the sky. At the time, a faulty propeller was to blame for the crash.
