No biggie. I'd read several books on the subject and had listened to a great podcast from BBC '13 Minutes to the Moon' and didn't recall the details. So I looked it up.

Niece asked me for pictures from my military time. I said I think the only ones I have are from over Panama. But I remembered the flight lead had been based in Panama and we went sight-seeing to view the Japanese mini-sub that had beached itself vs attacking cargo ships waiting to transit the Panama Canal. I had the picture and went on the internet to find an article about the 'Japanese mini-sub.'. Oh, the sub is there...but it was one of the first subs ever built and had sunk around 1870. So much for the 'Japanese mini-sub.' Flight lead buddy had flown there in the late 1970's/early 1980's and the real story, even then, had morphed into a WWII urban legend.
