Hi, i am an emergency services officer at a remote mine site in western australia. whilst scanning through my training session photos for pictures of a particular team member, i came across one that appears to show an object in the sky. the photo is one of a group of half a dozen photos taken in the same minute, on 13th september 2014 (according to the file information, all 05:52am - camera had wrong time set as it would have been early to late afternoon.) photos before and after the one with the "object" show clear sky. neither myself or any of the team members present saw anything on the day. the "object" appears to be disc shaped with maybe an antenna on top, and also seems to be reflective on its upper surfaces with either reflection or mist? on the undersurface as well. at the time the photos were taken we did not operate survey drones, and no aircraft flights scheduled for that time of day. we often see commercial aircraft operating at height, usually leaving contrails which are visible for quite awhile. this "object" seems to have appeared for a very short period of time, maybe a matter of seconds. the fire being extinguished was a diesel/petrol mix and would not have been throwing debris in the air. any ideas?
