A disc-shaped, flying saucer UFO was caught on video zooming past the window of an airplane flying over Iran. What is it?

The video shows a clip filmed through the window of a passenger jet. The YouTuber posting the video claims it was taken on April 19, 2012 while flying over an unidentified area of Iran.

Suddenly, a silvery, saucer-shaped object, with no lights or markers, flies past the lens and dives for the ground below. The camera follows the unidentified flying object until it dips beneath the windowpane for a moment, but catches up with it again as it finally flies out of sight.
