disc,s traveling east to west

About 1960 on a summer late afternoon approaching twilight I was about to  push a twin engine cessna 310 into the main hanger,I glanced over to my left toward  the Eastern horizon and noticed four maybe five opaque disc,s traveling towards me,they traversed from East to West and disappeared from view into the Western horizon in likely less than half a minute.There wasn,t any noise,or contrails or lights,just the  glow like from an opaque lamp.Having been raised at my parents FBO I had seen many various aircraft and these disc,s bore no resemblence to anything I had ever seen.
