From 2 miles south of Plevna (driving from south to north), MT my wife and I saw a fireball streaking down at a steep angle. It was a bit north of Plevna and was about half way up the horizon. It appeared for 1 to 2 seconds, bright flash, the fireball, a minimal fire streak with it. It was bright, then dim, then bright, then dim, then gone at about 1/4 of the horizon. We both said wow, meteor. We were excited to both have seen the "meteor". About 5-10 seconds later the same object went shooting back skyward along about the same line it took coming down. It appeared for less then a second, brightly, then was gone. It was really moving at a high rate of speed in both directions, nearly as fast going back up as it was coming down. It disappeared after that, we spent about 20 minutes watching to see if it would show up again. Once it shot back up we both knew right then and there that it couldn't be a "meteor". We both thought we spotted a UFO and were excited about it. We even tried to mentally ask it to reappear. Unfortunately that did not happen.
