Daniel Allen Butler writes: "if Smith did indeed go to the bridge around 2:10 a.m. as Steward Brown said, and took refuge inside the wheelhouse, that would explain why Trimmer Hemming did not see him when he went onto the bridge a few minutes later. Earlier, at nightfall, the shutters on the Titanic‘s wheelhouse windows would have been raised, to keep the lights of the wheelhouse from interfering with the bridge officers’ night vision: Trimmer Hemming would have been unable to see Captain Smith had the captain indeed been inside the wheelhouse, awaiting his end".
