I checked your website for information relating to a sighting from the U.S. Coast Guard Cutter Sebago in the Bermuda area in the late 1950s, probably 1957 or 1958.
At the time, it was well publicized.
In 1969 I read an article in ta newspaper which indicated that this was one of the most credible sightings on record and even listed the names of those who witnessed the event.
At that time I was assigned to a U.S. Coast Guard cutter.
One of my ship mates who previously had been stationed on the Sebago, a 255' patrol vessel, which was then home ported in Mobile.
He was one of the eyewitnesses who saw the UFO and was also the radar operator who actually tracked it.
He explained the situation as follows:
The Sebago was conducting an Ocean Station Patrol in an area near Bermuda.
As was common practice during the late night hours, the ship's engines were stopped, but still on-line and the vessel was merely drifting in the open ocean.
Around 2:30 a.m. a lighted object was spotted low in the sky off the starboard beam at a distance of only a mile or so.
It also showed up on the air search radar as being stationary.
At this time there were several watch personnel on the bridge, including the Officer of the Deck.
They watched the object for several minutes before it started moving slowly in a circular pattern around the ship.
When it reached the starting point it suddenly headed away from the ship at a rate of speed which was beyond the capability of the radar to measure.
The details above are approximations as I remember them and I am not implying that they are totally accurate.
As a former Coast Guardsman, I have always been intrigued by this incident and would like to know if you have any data related to it.
