I know no one did this, but would it be possible for someone to survive in the air pocket under collapsible B? I know Harold Bride was down there, but he came out and got on top of the collapsible. Could someone in his position have climbed under the benches and wedged themselves between the benches and the bottom of the boat? Would that have been a safe or wise thing to do? Or maybe several people could have gotten under the collapsible, and clung to the benches, keeping their upper body out of the water. Could anyone have survived like that?
