Telephoned report to NUFORC: Two ment were sailing on a 49-foot sailboat, and were located at 40.31 N/072.33 W, approximately 20 miles south of Long Island. One of the two men aboard witnessed an object in the northeast sky descend almost vertically down, level out above the water, and proceed to the south (left to right) for a few seconds. Suddenly, the object appeared to turn away from the observers, and moved very quickly out of their sight, heading to the east. Both witnesses described the unidentified object as being more or less circular in shape, with peculiar appendages extending off of it. It was metalic in appearance, and its surface looked almost shiny.Both witnesses are adult males, and both highly educated professionals. One of the two witnesses has been a commercial pilot for several decades.The two witnesses contacted the U. S. Coast Guard, which in turn forwarded the report to NUFORC. Please look for other reports for this date at some point in the future.
