The Andrea Doria stayed up for 11 hours, more than enough time for survivors to be rescued. In the case of the Titanic, there was another ship that saw the white distress rockets being fired and did nothing. The Californian and her captain were condemned by both the American and British inquiries. To this day there is controversy among Titanic historians as to whether Captain Lord of the Californian screwed the pooch. His supporters are called "Lordites," and they have constructed various elaborate explanations for his inaction. They claim that between the Californian and Titanic that night there were two other ships. One of which, for reasons not understood, fired eight white rockets and sailed away.
The Titanic fired 8 white rockets and 8 white rockets were seen on the Californian. And those rockets were reported to Captain Lord at least three times. And he did. . .nothing. All he had to do was wake up his Marconi guy and he would have learned of the distress calls coming from Titanic. And even if there was a mystery ship out there firing rockets, that just means Lord let some OTHER poor dumb b*stards to meet their fate. Pages from the Californians' scrap log for that night are missing and the fair log (the official description of what happened, written by the captain) makes no mention of the rockets.
Lord looks particularly bad in comparison to Arthur Rostron, captain of the rescue ship Carpathia. Rostron's nickname was "the electric spark." And when his radio kid (they were all very young) came to the bridge with the message that the Titanic needed assistance, they were putting the women and children into the boats, and here's the position, Rostron immediately ordered his ship to put about and head for those co-ordinates. He then told the kid to go back to the radio room and confirm the message. 90 percent of captains would have done it the other way 'round. Rostron realized if people were being put into boats, he needed to get there ASAP. Rostron headed full speed into the ice field, and after he'd pulled the survivors out of the boats, seeing ice bergs all over the place, wondered whether God had allowed him to penetrate the ice field without striking one of those bergs.
