Plane Crash Scene from the film Alive (1993) - (true story)

The Story of the Andes Survivors, which details a Uruguayan rugby team's crash aboard Uruguayan Air Flight 571 into the Andes mountains on Friday, October 13, 1972. After great debate, the starving passengers decide to eat the flesh of their dead relatives and friends.

This raises a question. What is the acceptable amount of time one should wait before committing an act of cannibalism? If these survivors began eating the others after one hour that might seem a little ghoulish.
