Yep that's 604 all right; I flew that airframe many times. Many years after the incident, US ATC still used to inquire if that was "the airplane". It sure generated a lot of interest.
Both the Captain and F/O are now retired. On occasion I have the opportunity to have a pint with one or both of them on the last Tuesday of every month. By the way the F/O did retire as a 767 Captain. The Captain retired as a 747-400 skipper.
Do they ever talk about the incident? Hardly ever, although Bob still does the occasional Japanese interview.
