Summary:

The unmanned aircraft system (UAS) was fitted with a third-party lidar pod for its planned survey mission which involved flights of around 8 minutes duration. As it commenced its pre-programmed route, it appeared to continue to climb above the 30 m height that had been set. The remote pilots observed that is was too high and attempted to land it imme-diately. The aircraft appeared unresponsive to the remote pilot’s inputs and it then com-menced an uncontrolled descent, rapidly increasing speed, until it struck the ground.
