Hi Michelle, I can put my dad & your dad together at the same place, same ship, same day. My dad was in the Merchant Marines and on the Antoine Saugrain when she was hit. He spent some time, several hours I think, treading water in the ocean waiting to be picked up.
So the ship info is definately familiar to me. But I think my dad was considered a merchant seaman and part of the Coast Guard, and your dad was radar--so will have to call my dad & ask him. My dad shipped out originally (I'm pretty sure) from San Francisco. Oh--just remembered--my dad worked in the mess--the kitchen--on the Antoine.
My dad is 83 & still has all his merchant seaman papers. When they had to abandon ship he made sure he grabbed those.
His name is Joe Dorris. Years ago I "met" someone online who was also on the ship that day but my dad didn't recognize the name, and Wikipedia says there were about 450 people on board. But will call him & see if any of your info rings a bell. He loves talking about it now, and has amazing recall. Will be interesting to find out if he had any contact with the guys in radar. Or if your dad ever ate any of the food my dad helped cook!
What an amazing coincidence!
