Object over Isfahan, Iran filmed by Japanese tourists.

Interesting how good videos come in waves. I've been looking at obvious hoaxes for a week. Now, suddenly, half a dozen good videos or reports appear. There is no reason to doubt the legitimacy of this video, but it's possible that the object is a plane, although the absence of the telltale vertical stabilizer suggests otherwise. (Plane videos mistaken for unknowns almost always reveal a bit of the vertical stabilizer, even if the angle of the video makes the wings impossible to see.)
