Was Sherpa Ang dorjee responsible?

The cylinders were stashed at the south summit, and they weren't empty. Andy Harris was confused and thought they were empty but this was not the case. It's thought that Andy was already suffering from HACE (as Scott Fischer also probably was) and this affected his judgment and ability to read the dials etc. correctly.

It was Doug hansons fault , shet I hate badmouthing the dead

Sandy Pittman was to blame for it all.. A rich socialite b*tch who had someone vital to the crew dragging her up the mountain.

It's not PC to hold the Sherpas accountable and usually their key role in the disaster is carefully avoided in the discussions, but having read several books and interviews with survivors on the subject, it's impossible not think their dereliction of duty on that day was the ultimate cause of all the delays and subsequent problems that resulted. Nothing to do with the cylinders, but them not doing their extremely important job that day and fixing the lines.

Lopsang and Ang Dorje were supposed to work together and fix the lines before any of the teams had arrived, precisely to prevent the bottlenecks that occurred. They didn't do it and both repeatedly lied about the reasons and even tried to blame the leaders who had died. They changed their stories multiple times, but finally settled on saying the plans had been changed at the last moment by Hall and Fischer for some inexplicable reason and without telling anyone else, not even the other guides, despite the fact that both head Sherpas left on schedule with all the rope needed to do the job. It is utterly absurd to believe Hall and Fischer told them not to fix the lines and then were flabbergasted that they hadn't been fixed when their teams arrived. The Sherpas who had proven themselves to be very brave and skilled climbers didn't do their job that day and wouldn't take responsibility for it.

Lopsang instead decided to short-rope Pittman for very unclear reasons, she didn't ask him to. Ang Dorje then refused to help fix the lines because Lopsang wasn't doing the work too. He sat around acting surly instead of helping during the bottlenecks. They clearly let their ego's and petty rivalry get in the way of doing their jobs. It's hard to see this tragedy happening if they hadn't been delayed by so many hours due to not having any fixes ropes before the storm came. It cost them such vital hours.

Ultimately it was Scott Fischer and Rob Hall's faults. They were the team leaders. The Serpas are hired help. They can only do what the team leaders tell them. But it was Fischer and Hall's fault.
