SEATHLElT
Cn or about l9h5cSf, le Se terber 1960 I hagpered to look up at the
sky and spotted a brirht object. When I first noticed the object it
appeared to be comine from the Southwest and treveling en a fixed
course toward a northeast direotion. I cslled my fem'ly to see it.
In the meen time I went over to a friend of ours (Captain
to have him lcok at it.
After watching the object for ten minutes I caliled our Base Weather
stetion to check it out. When I returned to further o'serve the object
it hed disapreered leaving no trace. For vears I heve been interested in
Eche Satellites. This UFC wasn't like the others. It seered to be on a
straight course and very steady. There was no turbling cf satellite
whare the lidhts came of'f or on. It was very bright from the time I
noticed it and until it diseppeared.
I an forwerding this report join Micw later.
