Roger Marsh of UFO Examiner reports that "a triangle UFO flying higher than any conventional aircraft" was spotted during Ozzy Osbourne's performance at the Ozzfest 2010 kick-off concert on Saturday, August 14 in Devore, California. "The shape was triangular with rounded tips," one concert-goer was quoted as saying, according testimony from the Mutual UFO Network (MUFON) witness-reporting database. "The color of the craft was a pale gray. The middle looking on edgewise was slightly rounded and thicker in the middle, which held three round lights in a line strobe-like. Colors were green, yellow and pinkish purple. The lights were like a strobe that blinked and flashed 3-5 times before it disappeared behind a tree that it fit behind."
