The movie is about Jerri Nielsen who was lifted out of the Antarctic base in October 1999 by LC130 of the NY ANG which was done earlier than normal because of her condition. They couldn't attempt it any earlier because it was too cold.
The comments about Kenn Borek Air being the actual rescuers mistakes the pickup of Ron Shemenski in April 2001 from that same Antarctic base as Dr. Nielsen's pickup. NSF apparently decided that the Otters would probably have less trouble (they can land in somewhat lower temperatures than LC130s) and be easier to support for the mission and had the LC130s recalled.
