Mistretta’s source claimed there were a few annotations on the back of one of the photos: “Official photograph. Not to be released. CT.” and “Unauthorized Disclosure Subject. Security Certificate SSN 674. Criminal Sanction.”
These inscriptions created an out of the ordinary twist to those analyzing it.
SSN 674 was the official classification number given to the USS Trepang. Furthermore, the nuclear submarine was indeed in the area at that time. The report also mentioned the presence of Admiral Dean Reynolds Sackett aboard the submarine, which can be verified here.
It is unclear whether the encounter involved two distinct UFOs or a single one capable of shape-shifting, but the photos appear to show two distinct objects, one shaped like a cylinder, the other like a triangle.
Unfortunately, more information regarding this interesting case is absent but we will be the first to present it if more information arises.
