The Sherpa who was missing, show up at Base Camp, which is nothing short of a miracle. The Sherpa was separated from his group and did not have communications equipment.
Apparently there was a "traffic jam" of around 150 people between Camp IV and the Summit. It appears that the same ramshackle, no name Expedition Companies who "charge less, for getting to the Summit" are still at it and folks are naive enough to pony up cash.
Obviously, some haven't learned from events from May 10, 1996.
