Struck trees during aerial survey, Generals Lane, Chelmsford, Essex, 25 April 2019.

Summary:

Flight parameters were set using the software and the operator allowed a buffer zone from the trees that surrounded the field being surveyed. However, towards the end of the flight the drone struck a tree. The operator stated that the buffer zone had not been sufficient to allow for the turning circle of the drone at the end of one of the flight legs. The damaged drone was recovered from the tree.
