OBERHAUSBERGEN Wednesday 8 August 1973 luminous dot
information not communicated
Unsolved -lack of info


The UFOs move "from the Graffenstaden forest" thus from the Southeast (That forest is 10 km away from the witnesses) "to the EDF plant on the Rhine" thus still in the Southeast but more to the East then "turn around and go South."

Visually, from the witnesses position, they appeared in the Southeast, moved a little to the east, then went back to the South-East but mot to the West than the place where they were first seen.

As there is absolutely no useful detail, the things being described only as "six luminous spots," it could have been airplanes, helicopters, ot whatever. The strangeness of this case leaves much to be desired with the little information provided, and Charles Garreau gives no source that may have yielded more information.

And all this being reported by "young girls", maybe very young.


Possible planes or helicopters, insufficient information, no strangeness.
