Pretty sure that was just the moon in that shot.

I'd like to point out that the video in question was taken with a Canon A510.
The author of the video also stated:
The brilliant fireball appeared to be closer than the airplane in the upper right corner of this video. I made the movie using a Canon A510.

And this puts to rest the alleged UFO in the upper right corner (R.I.P. †).
Regarding what it was, i'd wait until they (hopefully) find the crash site: so far, the nature of the object is uncertain.
