I would not want to set a precedent of the CG not attempting/performing rescues of adventurers who get in over their heads. Someday I might be the one who planned piss poorly.
Nor do I, but they make it sound like the Explorers Club is being altruistic, when in reality they were just looking after their own interests.
You don't see the Explorers Club lobbying the White House to get the USCG search longer then a boat of fisherman go missing actually in US waters.
