Lightoller said the ship had turned around when he was sucked underwater. That was before he made it to the collapsible. When he came to the surface again the broken stern was facing the opposite way as survivors saw it turn around after she broke. Jack Thayer was on the collapsible boat and described the ship turning around and looked up and saw the propellers above the collapsible boat and thought they were going to come down and smash the boat. Lightoller got onto this boat after he reached the surface. Since he believed the ship had turned around while he was under the water (before he got onto the collapsible) it would mean the boat was not pushed away by the waves created by the 1st funnel falling as it was a great distance away, which is why it may have been the 4th funnel that fell backwards and fell near the propellers where the collapsible boat was. Another possibility is that the broken stern was turning around before the bow had submerged. So it could have been the first funnel and the stern was hovering over the bow section as it turned around. Lightoller did not tell the official Inquiries what he later stated i.e. that the ship had exploded and turned around when he was under the water, because the Inquiry would have been puzzled how the stern section and propellers could be hovering above his boat while the bow section was sinking separately and the first funnel was falling near his boat. It would mean the ship was broken in two.
