What a silly question!
You would obviously take the survivors to their home towns where you would then ask them if they wanted to be buried or cremated and then wait around until the effects of the plane crash kill them. If they refuse to die there and then keep crashing the plane until they eventually all snuff it.
If i survived a plane crash on the Canada/ US border i think i would like to be buried at sea (or in foundations of a big important building).
