At the beginning, the setting starts out in a plane, then, it eventually turns to an hospital, more so, changing of the setting builds some sorts of suspense. Reason been he doesn't know where he is, where he's heading to, neither does he know what is going on, same as you too. As it was described in the story, when the character was pulling himself to the window, everyone was wondering what he saw and what exactly was going on in the window. Hence it gives a suspenseful and mysterious mood.
