Strange object captured over Shanghai's Pearl Tower.I was in Shanghai with other American students in a bus travelling to the Shanghai Hotel for the first time. I decided to take some pictures of the Shanghai skyline with my digital camera when I shot this photograph. There were not any objects in the sky before or after I took this picture, at least none that I or anyone else in the bus noticed. The tall tower building you see the object next to is the Pearl Tower, the tallest building in Shanghai, China. This picture was taken in a moving bus without flash, mind you there is still a window between the camera and the outside. The dark outline on the right of the picture is the curtain. The dark spot just left of the middle of the picture is a smudge that appeared in several of the pictures taken out of the same window overlooking the same area. Strangely enough, I was never able to identify the location of this imperfection on the window but I give it enough doubt to believe that it was not anything outside. If you zoom in on the object you can see its detail. It is reflecting the sun from the same angle as the tower and you can even see a bit of a shadow on the bottom of the object. I know it is not an aircraft because there weren't any in the air before and after taking the photo. I had seen a few aircraft in the air that day but none had been so reflective and not one was even close to this shape. I also know it is not a reflection of anything from the outside creating a glare on the window, because the glare would have bled out more on the dusty windows. There is definitely something out there in this picture; the pinpoint detail that can be seen really shows it. I showed this picture, instantly after taking it, to the other students in the bus. There were mixed explanations. I don't know what it is, so I leave it up to you to interpret what it may be.((NUFORC Note: We see a bright glare in the sky, where the source indicates it should be, but we do not know what it is. We have no reason to believe it is necessarily a genuine UFO, but it is unidentified. PD))
