Three types of UFOs in the summer of 1968 in Western PA.

There were 3 incidences in the summer of 1968. The first one is at dusk in the sky I saw 3 oval saucer shaped UFOs that appreared to be of a shimmering light almost like they were not quite solid is the only way I can describe them. They were over the woods nearby and if they were 20 feet in diameter they would have been approx  one half mile away. They moved forward and backward and zig-zagged back and forth. I heard no sound. I ran away  from the scene. The same month I saw a number of smcall red lights in the sky at night which lasted for hours and I heard neighbors commenting on them. They didn't appear to move much but would disappear then appear. There were over 20 or 30 of them more on the horizon of the sky than overhead. Within days of the above I saw an extremely bright starlike light directly overhead in the evening again. It appaeared to look like a shimmering star but was as big as the sun in the sky. Slowly over a period of maybe an hour it shrinked to the size of a small white light. I thought of getting my Bebe gun and shooting at it as it seemed only a few hundred feet up ( I was 16)  but my good sense prevailed.
We will attempt to locate other observers for corroboration.  PD
