Here is what could be a picture of a UFO, except ...
First the alien spacecraft explanation:

Clearly this shows a cylindrical spacecraft, descending towards the left of the picture. It is using a very unusual drag-chute to slow it down. American and Russian spacecraft don't use this kind of chute, so it is probably an alien design.
But there are some things wrong with that explanation:
(a) "Clearly" - the picture is actually clear and in pretty good focus. This just doesn't happen with normal UFO pictures.
(U) It's not unidentified, I know what it is.
(F) It's not flying in the sense of descending towards the left under some sort of control.
(O) Ok, it is an object.
Of course it is a kite. A very interesting one at that.
If you look closely, you can see the strings that control it on the lower right. The wind was blowing from right to left. The cylindrical part is the tail of the kite.
OK, due to the criticism I now have found an improved picture of the descending (crashing?) alien spacecraft.

This one is obviously a night vision camera picture, you notice the greenish hue and the blurriness. Typical for the night vision cameras. As you can see the spacecraft it in a steep decline, and it crashed soon after.
