Question: When the trio first found the tail, Nando writes "Go Up 18 Still Alive" in the tail. The fuselage is lower than the tail because after the tail was detached, the fuselage slid far down. The trio had to climb up the mountain to find the tail. So why does he write "up" instead of "down"?
Question: I'm curious as to why Paéz is the narrator in the beginning and end of the film, when the movie focuses mainly on Canessa and Parrada as main characters. Almost all of the boys are alive today, and even if they weren't it is not Páez himself who is being interviewed but John Malcovich as Páez. So I'm still curious as to why they chose Páez instead of Parrado or Canessa, as they are both alive today.
Question: What does Cannessa mean when he says "I had no premonition. So much for ESP,"?
Answer: ESP stands for Extra Sensory Perception, the ability to see into the future or predict it in the form of a premonition. He means that whatever happened, he literally didn't see it coming.
Answer: Keeping in mind that some parts of the audience were not familiar with the details of this story, using Paez as the narrator retains some of the suspense of Canessa and Parredo's journey across the Andes. If the audience is not told at the start that they survive, at least some viewers may have considered that one of them may die during their trek to civilization.
