I was doing a gutter inspection with my Mini 3 Pro plus some general photography for the charity I volunteer with (a London Youth Club and Community Centre with food bank). My spotter had just said “ah, birds” as a flock of pigeons out of nowhere was all around the drone. Within a second a pigeon collided with the drone and it dropped out of the sky. The collision folded in the right rear rotor arm (causing the crash) . It landed in some longish grass just missing a giant container full of asbestos covered in a tarp. Only damage was one cracked prop. Sadly I wasn’t shooting video at the time.
A reminder that even a super reliable carefully pre-flight checked drone can fall to the ground at any time without warning. Insure them and avoid flying over people wherever possible.
