In the footbridge problem, the player is standing on a small bridge over a trolley track. Again, there is a trolley with no brakes heading very fast toward five people. It will hit and kill the people if nothing stops it. They cannot get out of the way. There is also a second person on the footbridge. If the player pushes this one person off the footbridge, then their body will stop the trolley, saving the five other people. But the one person whom the player has pushed will die. In this problem, the person the player would push is big and fat enough to stop the trolley, but the player is not.
