Twin cylindrical craft in stationary formation over Bavarian Alpine town of Mittenwald 1996Observed single craft moving to SE at high altitude in visibility unlimited with sun reflecting off highly reflective surface of craft. As I observed what I thought was an airliner of a type that doesn't have a broad wing that is sometimes not visually prominent from that altitude, I became aware that its speed did not seem consistent with an airliner as it eventually slowed, ceased forward motion, an maneuvered to 90 degrees from its original flight path, and became stationary directly above the mountain peak at the base of which is the German town of Mittenwald, in the Bavarian Alps close to Italy, Austria, and Switzerland. Soon I noticed another identical craft approach the first from the original course of the first, coming to a stop parallel to the first, and remaining so for the time I was observing from the window of the train as I was awaiting it to begin the trip back to Munich. My brother and his wife were with me, although only my brother confirmed the phenomenon as he only had a window seat opposite from me. This is a very busy tourist destination, and the mountain over which the craft hovered has a cable tram to the top (8,000'-10,000'), where there is an observatory, and ski runs, so there had to be many other witnesses. As I think back, the sky was so clear that I feel it is very likely that I was observing very large craft maneuvering outside the Earth's atmosphere.((NUFORC Note: Date of sighting may be approximate, although the witness does not indicate that fact. PD))
