Both Accessair and APP are correct; the aircraft was a FH
-227 (american-made F-27) and the team was a RUGBY team, not a soccer team. The boys were students at the Christian Brothers school in Carrasco, Montevideo, Uruguay, a school started by Irish Jesuit priests after WWII. Rugby is VERY popular in Uruguay and in Argentina and both nations sent teams to last year's IRB World Cup in Australia.
The cause of the accident was pilot error. The pilot initiated his descent into SCL
before he should have, caught some air pockets, and was unable to climb and avoid the jagged peaks of the Andes.
The survivors totalled 16 out of 42 original passengers/crew and spent October-December in the Andes; NO vegetation/animal life at those altitudes and, obviously the boys resorted to extreme measures (we all know what they were) to stay alive. The idea was that of the 18 year-old medical student, Roberto Canessa (played by Josh Hamilton in the film)- he realized there were no other options.
Two boys, Canessa and 'Nando' Parrado (played by Ethan Hawke in the film) made the arduous journey to climb down from the mountains and find civilization.
Quite a show of human spirit if there ever was one!
