ADDITIONAL REMARKS BY OBS22VER: lumediately following the disaopearance of
the object 7 observed a sinczle contrail that suggested a Jat pieeenea, The
contrail appeared alnost directly overhead and on a course of SE to Wi on a
sweeoing curve. The contrail was viewed Sast of the point of disappearance
of the "object".

COMMENT s i iii appeared sure that he saw something out of the ordinary
He evkdenced no wxcitement over this sighting. In my opinion his guess as
to the altitude would suggest he saw one of the satelites, possibly the

inact

gon" satelite.
