This event took place on September 24th 2013 heading west on Arapahoe Rd .My girlfriend observed the hoovering of a disc like object in a Southwest direction towards the mountains at approximately 6:50pm. What struck my curiosity is that the object did not move or have sound. It didn't appear to be a plane or anything i could describe. We we're driving in the direction of the sun however,we could see a plane moving at the same time considering we were close to Centennial Airport. I quickly grabbed my phone and took two pictures then the object vanished without trace.. The pictures will be enclosed .. Please examine them and maybe you can tell me what i saw.. This will is exciting for me to find out if in deed i had an encounter with a UFO... Since we are being kept in the dark about the true knowledge and existence of extra terrestrial life.. If u find this to be a true encounter please share this with everyone and anyone...Thank You !!!!
