It has often been assumed that the senior officers and crew were not aware or informed that the ship would go down. They may have heard she was taking on water and would sink down a few feet, but there was clearly a good deal of confidence that the pumps would keep her afloat. e.g.
Mr. Ismay
"I met Mr. Bell, the chief engineer, who was in the main companionway. I asked if he thought the ship was seriously damaged, and he said he thought she was, but was quite satisfied the pumps would keep her afloat."
4th officer Boxhall
Q - Were you convinced, when you took to the boat in which you left, that the Titanic would go down? (shortly before 2am)
A - I was quite undecided about it.
2nd officer Lightoller
"I'm afraid my own confidence that she wouldn't or couldn't sink rather conveyed itself to others."
3rd officer Pitman
"We then cast the boat off and pulled away some safe distance from the ship. It was not for an hour that I realized she would go, an hour after we got into the water. I quite thought we would have to return to the ship again, perhaps at daylight. My idea was that if any wind sprang up we should drift away from the ship and have a job to get back again."
Symons
"I expected to go back with my passengers and land them aboard the ship again."
Jones
"I thought they were only sending us away for an hour or so, until they got squared up again.....Until they got her pumped out."
Jones - was also given instructions from Captain Smith.
"He told me to row for the light, and land the passengers and return to the ship."
Crawford
"He pointed to a light on the port side, the two masthead lights of a vessel, and told us to pull for there and land the people and return to the ship.....We were told to make for the steamer and return to the ship......He pointed in the direction of the two lights, and said: “Pull for that vessel; land your people and return to the ship.” Those were Captain Smith’s words."
There was nothing to suggest from their words and more importantly from their actions that the ship would completely sink in 2 hours, in fact they appeared to believe the opposite and with confidence. A new Inquiry which examines, evaluates, and revises the old Inquiries might tell us why. Was the damage really as great as the Inquiry led us to believe? Did officials instruct several witnesses to conceal what really happened i.e. Barrett covering up a blunder which accelerated the flooding, and put the blame squarely on the iceberg for the rapid sinking of the liner? Did something occur within the ship during the evacuation e.g. turning the wrong valve, or re-opening a watertight door? The contradictions in the testimonies leaves many puzzling questions. Why were most of the firemen kept out of the Inquiries? Why did the few who did testify fail to mention the orders given after the collision e.g. Half speed ahead, and slow astern, and also why the lights failed in the boiler rooms and if some other electrical or mechanical failure had taken place.
A new Inquiry which includes all available sources of information from experts and survivor accounts heard outside the old Inquiries might reveal a clearer picture of the truth.
