the two climbers were part of a seven-member Korean team climbing from the southwest face of the world’s highest mountain.
The AP story suggests two things: the Filipinas actually chose the better (if more arduous) northern route (on the Tibetan side, or China, depending on whose history you subscribe to). And their descent on the southern (Nepalese) side is more perilous than previously reported. (See this IHT story too.) Note that one Everest climber dies for every 10 or so who summit.
Godspeed, Carina, Janet, and Noelle.
