Serving as lookout on a Navy Radar Picket ship USS Durant, I spotted a pinhead of very bright light overhead. I notified the Officer of the Deck. He called other higher ranking officers and chiefs to the upper bridge to observe.
Though long ago, I still remember it as at about 30,000' to 40,000' altitude, and changed direction very rapidly. It moved about 3° to 10° as viewed from sea level.
As a lower rank enlisted person, I was not informed of what measures took place. It seems there was rumor or speculation that jets were scrambled from Hawaii to check it out. Not a great distance for tactical fighters to fly.
