In September 2017 astronomer Marc D'Antonio, chief video analyst for the UFO group MUFON, said at the Devil's Tower UFO Rendezvous in Hulett, Wyoming, that the U.S. Navy logged unidentified fast underwater objects under a "Fast Mover Programme". The British tabloid The Sun reported his claims.[1]
The account
D'Antonio, who ran a special effects company called FX Models that did Navy contract work, said the Navy offered him a ride in a submarine in the North Atlantic as thanks. Sitting at the sonar station, he said, he heard the operator call out "fast mover" and report an object travelling at several hundred knots. After a second sonar set confirmed it was not a malfunction, the executive officer told the operator to "log it and dog it", which D'Antonio took to mean log it and bury it.[1]
The "programme"
D'Antonio said that four years later, during more Navy contract work, he asked a senior naval figure about the "Fast Mover Programme" and was told he could not talk about it, which he took as confirmation that the program existed and that such objects were common.[1]
Context
The Sun noted that most submarines and torpedoes can manage only about 40 knots, so an object at several hundred knots would be extraordinary. Later, Congress asked the Pentagon's All-domain Anomaly Resolution Office to look at underwater and "transmedium" reports.[1][2]
Assessment
The claim rests on D'Antonio's recollection of one voyage and one conversation, and no document confirms a program by that name.[1]
