Had I been in one of the boats I certainly don't think I would have it in me to have looked.
I always felt really sorry for the members of the ships's crew in the boats whose shipmates included family members. Was their brother, brother-in-law or cousin still on the ship as she made "the final plunge" or if they had made it into one of the boats ?
No doubt dreading the real prospect of having to go back home to Southampton and have that long, awkward, heartbreaking conversation with their elderly mother or father, or sister etc that "the last I saw of our Bill, he was putting bread into one of the boats" or "the officer ordered me to stay in the boat and your Jim went aft, I never saw him again."
