Route Notes	Summit party of 3 left C3 0:30 am NST and on top 8 hours later. Buendia and Tittle left ABC together on 21 Sept. Schmidt (see separate team) 1 Oct 2001 said Tittle left because he needed more attention and guiding: he found himself alone on a ridge and did not want to go on without more help from leadership. Tittle went to Bangkok from KTM and was found dead in his hotel room from drug overdose.
Accidents	Buendia developed symptoms of altitude sickness and left ABC (also lost motivation)
