Object gave off a bright flash of light and disapearedUnidentified object spotted driving East on I-26 just south of Asheville, NC. Object appeared to be moving at the speed of a large low flying plane and was cigar shaped. I was traveling near the Asheville airport, so I thought it was only a low flying plane at a distance of approximately 3 miles; however it seemed rather odd shaped for a plane so I continued to glance up at the object while driving.The last time I looked up at the object it appeared to take a sharp turn south and gave off a bright silver flash of light and disappeared. It was bright enough that it made me close my eyes for just a split second, then look back only to find the object no where in sight. I watched the area that the flash came from for about 30 second, thinking I would see the object flying off. The object had disappeared.
