China, Circular. 10-20 seconds Along Yangtze River at Qutong GorgeI am a Singaporean and was on vacation cruising down the Yangtze River on cruise ship Century Sun on 1 November 2013. It was a hazy rainy early afternoon and we were cruising through Qutang Gorge towards Chongqing.I was aiming my compact Lumix Panasonic camera on the red structure perched on the mountain side and decided to take some shots.Unknowingly, I captured an UFO by accident. I was not aware of it until when I sort out my digital shots much later after returning home.On close examination, I believed that it is an UFO of an enormous size as compared to the red structure and the two peaks in terms of scale.It cannot be a sun flare or lens reflection as the background mountains were misty and the shot was taken on an open ship deck.It cannot be a speck of dirt too as the circular craft looks lighted in yellow and huge in size. There were no people present on the ship deck as it was raining. What sort of object is it remains a mystery. I am looking for a plausible explanation .More details: The shot was taken with a 24mm leica lens 3.8x zoom compact camera from the open ship deck.The area where the UFO appeared was a secluded and an isolated region near the Qutang Gorge with no people found along the river bank.There is no possibility of other planes found in the area as it is a moutainous region and risky to manoeuvre at low attitude. It was also a hazy rainy afternoon.The enormous object seem to be moving a very high speed as the next few photos taken within second, were without the object.
