@ColtSTaylor gotta love the Lad Bible site and all its misspellings! It really does look like a mylar balloon, but the article says "the mysterious, square-like object shoots out of the clouds and past Arteaga's cockpit in a matter of seconds."
BTW - the video link is no longer working/active ...!?!
