The U.S. Navy says it still believes that a collision between the destroyer USS Fitzgerald and a container ship occurred at 2:20 a.m., even though Japanese coast guard officials say it happened about an hour earlier. Cmdr. Ron Flanders, a Navy spokesman, said Monday that the destroyer reported to officials that it collided at 2:20 a.m. Saturday with the Philippine-flagged container ship off the coast of Yokosuka near Tokyo. Seven American sailors died in the crash. Coast guard officials said they have revised the time of the collision to 1:30 a.m. from their earlier estimate of 2:20 a.m. after interviewing crewmembers of the container ship, the ACX Crystal. A track of the container ship’s route by MarineTraffic, a vessel-tracking service, shows it made a sudden turn as if trying to avoid something at about 1:30 a.m., before continuing eastward. It then made a U-turn and returned around 2:30 a.m. to the area near the collision.
