Save your life or save others' lives?

Say you were in a situation where you could either save your life at the cost of other lives, or you could save others' at the cost of your own life- which would you choose?
I ask because of the man in the Air Force who recently died in a plane crash. He knew the plane was crashing, if he jumped out and parachuted down (thus saving his own life), the plane would have crashed into a neighborhood potentially killing many. But he stayed in the plane and made sure it crashed into the ground in a remote area, because of his choice, he lost his life. 
Obviously, he's a hero. But I think since he's in the military he's a hero no matter what he chose. He left behind a wife and two young children.
So be honest, what would you do? Save your life, or save others?
