John,
That was the only open sea sucessful ditching of a Pan American Stratocruiser. Pan American lost at least one other in the Pacific. Can't recall if it had left SFO or HNL but it was lost with all pax and crew. I believe NWA lost one off the cost of Oregon and perhaps another one after taking off from SEA with the cowl flaps wide open. Like everything on me, my menory is failing.
I do recall the advent of DME on the Pan Am 707 and it had nothing to do with the work that you speak of. I spent a little time in the left rear corner of the 707 flight deck and even that is starting to look dim at this hour.
