UFO Sighting in Sharon, Massachusetts on 1977-04-30 16:00:00 - 3 capsule shaped shiny objects, silent, fast moving

Late afternoon walk on norfolk place in sharon, ma. we were looking at a large jet liner making a slow lazy turn, probably headed to green in providence, ri. at that moment, we witnessed 3 bright. shiny aluminum shaded objects fly by at incredible speed. they were capsule (like nasa mercury/gemini) or somewhat bell shaped, moving east to west, silent, no emissions, at an incredible speed. they were visible perhaps for 2-3 seconds but were very clearly visible. my companion and i looked at each other and both asked if we had seen "that"? although this event happened in 1977, it has always stayed with me. i can see it as clearly today as i did in 1977. to date i have only told three family members of this event but it has always haunted me.
