This individual in question was much better prepared for the adventure than many, and he almost made it. Global communications, airborne help etc makes these much safer than ever before, he was also airlifted out alive, and at least to my eyes also take a lot away from the true challenge*. Practically all people skiing to the South Pole ski just one way and are airlifted out, but still expect the same veneration as the old explorers (these contemporary guys do not actually explore anything) who had to first to get there, but also BACK, which is the harder part actually. Mr Worsley at least was an honest old school man and tried to get there and back again under his own power, so much respect to him.
*) I suspect he did not call for help earlier, as he also understood the old rules of the game: you are alone in this. In the old days we would not have known what happened, only after a few years we would be more or less sure he had not made it, and his body would be possibly found a hundred years later or not at all.
