When the Others see the plane breaking up mid-air, Ben sends Ethan and Goodwin out to each site and tells them to get lists in 3 days.

GALE: You run and you can make that shore line in an hour. Ethan, get up there to that fuselage. There may actually be survivors; and you're one of them. A passenger -- in shock -- come up with an adequate story if they ask. Stay quiet if they don't. Listen, learn, don't get involved. I want lists in 3 days. Go.
