AAIB investigation to DJI Phantom 4 RTK, (UAS registration n/a): Loss of control due to detached propeller, Newtongrange, Dalkeith, Midlothian, 2 December 2020. The AAIB Final Report was published on May 20 2021, and the following is an excerpt from it:

The aircraft rapidly descended from a height of 70 m (230 ft) where it struck the ground in the rear garden of a house. No persons were injured.
