5 to 6" diameter light, extremely fast, silent, made an impossible inside 45 degree turn, and sped away horizontally.

This report goes back to Autumn of 1957. One object. I first noticed the entire area outside the rec room illuminated like day.  Jumped over the couch to the open door and looked up at this huge light moving down toward me and 45 degrees. When its size (at arm's lgth) reached 5 inches in dia, it veered away horizontally and out of sight. It was as though I could feel the heat of the light on my face..no detail to see, literally like looking into a headlight. Absolutely no sound. No other lights visible. Altitude...as it vanished may have been 60 to 100 ft.  This happened so fast It is difficult estimating its'size and altitude.  Duration of sighting about 3 seconds. I don't recall the moon being out, but it was dark out, cool and clear. I was wondering if others may have reported this. Should have been seen by many!
