In real life just left there?
There are lots of stories of people dying near Everest and climbers leaving them there for various reason such as seeing it more important to get to the peak, or conditions too dangerous to save them. There's a story of a climber being passed by very many and none of them doing anything.
Like that Towering Inferno where they came up with ingenious plans to save people, but in real life they did very little to save ones above fire in WTC.
