January 22, Atlantic Ocean. The map in the seatback shows that we are flying over the Charlie-Gibbs Fracture Zone. I consider writing down the name so I can research what it is later. But I need to learn to do something like that right away. I read in Wikipedia, and get to a page from 2009 where someone from the crew of a U.S. Coast Guard cutter describes the 1966 voyage during which the first evidence of this fracture zone was discovered.
