Here's Johnny come lately, what it took the better part of an hour to compose this post, and I'm not right anyways.
The Mariner G for George was lost in Antarctica in 1946 during Operation Highjump. Amply supplied, although three of the crew died in the accident, the rest were rescued by another Mariner and a concerted effort with launches, from the Pine Island. I do not know her call sign.
Here's a model I built about a year ago of the Pine Island, with a lot of PE, showing the recovery of a Mariner in Arctic waters. It's a good story, and hopefully the right one. Mariner operations were aided by the expense of bunker fuel onto the sea. JATO was the rule of the day for takeoffs.
I've a Mach 2 Mariner "in the stash", my heirs will chuckle over it at the funeral.
