There is a moment at 17:15 on this flight log when the pilot switches from position hold to offboard mode and the vehicle begins to lose altitude. From looking at the z position plot more closely, the descent begins before the offboard mode begins and there is a shot period of time where there is no flight mode shown on the plot. Any ideas on what could cause this?
