Task: Question Answering
Input (English): A group of teenagers verging on adulthood are to spend a year in a remote village in Indonesia, learning to live on the same terms as the people in that village. Their teacher is going along as well, but he decides to make a little extra money along the way: he cancels out on their scheduled transport to the village's nearest airport and hires a decrepit plane and its pilot, who's seen better days for his income. The deal is that the pilot will make out the receipt for a higher amount than the teacher actually pays. The pilot, in turn, makes a deal with drug dealers to make a delivery, so when the plane takes off with the students aboard and the teacher in the co-pilot's seat, it isn't flying the direction the teacher and the students require to get to their destination. The plane has mechanical troubles, and lands in the water near an island while the pilot checks it out. He informs the teacher that he'll have to return to an airport for repairs, and teacher says he's going along to make sure the pilot returns. That leaves the students on the island. While they wait, some of them explore, but one dies in the rising tide after a rock traps his foot against another rock. As night approaches, they decide to leave the beach and find a better campsite. They leave a note for the pilot and teacher that they'll listen for the plane. Meanwhile, the plane is having even more mechanical problems, as the pilot gives a grim comment to the teacher. Many of them quickly discover they need a leader to make decisions and serve as arbiter in disagreements. Having accepted one boy, they then decide on some rules, such as lavatory rules. Some days later, the airplane is spotted next to the shore of the island. The leader leads them cross-country to the plane to check it out, and he briefly gets caught in quicksand and panics, but is extricated without threat to his life, although a passing snake rubbing behind him freaks him out. 
Question: Who mentions that he has to fly the plane to the airport for repairs?
Output (English): the pilot
