Very early on in the emergency, Benoit Pickard found an access route via a door leading to the second-class stair case, but that door is supposed to have been closed and locked not long afterward
Who said so conclusively? Pickard found
a door from Third Class leading to the Second Class areas open and went through it, eventually making it to the boat deck on the starboard side, where he was rescued on Lifeboat #9. So,
he could not have known that the door through which he had come was later locked. Other survivors would not have known which door Pickard used and so
they would not have been in a position to claim that it was later closed and locked.
The other official 3rd class access routes (from the well deck, from Scotland Road via the first class stair case, and via the stairs from the well deck to B deck) were all locked, closed, blocked
Paradoxically, the first Third Class passenger to get into a lifeboat was not only a man, but he (Fahim al-Zainni) sneaked into Lifeboat #6, a port side "Lightoller's boat"! Thereafter, there were a few Third Class passengers getting into port Lifeboats #16, #14 and #12, the first two of those being launched a few minutes before #9 on the starboard side and #12 soon afterwards. The point I am trying to make here is that several Third Class passengers including men had found a way up to the boat deck by 01:00 am and so there must have been ways for those who looked for it. Most were women and children, but in some cases there must have men who came with them but were not allowed in on the port side. Still, Zaini (#6), Bernard McCoy (unconfirmed but almost certainly #16), Fang Lang (#14) and Gurshon 'the cat' Cohen (#12) all found places inside lifeboats before or about the same time as Pickard in #9 on the starboard side. Under those circumstances, it is fair to assume that there must have been a lot more Third Class passengers scattered about on the upper decks and not sure where to go.....
but they had got there.
I reiterate that IMO the doors that many Third Class passengers found locked when they tried to get to the upper decks were those that had been locked during normal voyage before the disaster - a common practice to segregate steerage passengers in those days - and were simply not unlocked afterwards. Under normal sailing conditions, most Third Class passengers would have known about that segregation and accepted it as the norm. Since the question of Third Class passengers getting to the upper decks out at sea during a normal voyage could not have arisen anyway,
many of them might have wrongly thought that those doors and gates were their only access routes to get above and panicked when they found them still locked after the collision. As for the Third Class stewards, they would have been overwhelmed by the numbers, language barrier and above all uncertainty that they had to deal with. 2 hours and 40 minutes can seem quite long at first but when you consider the size of the
Titanic, the number of people in Third Class (even when not filled to capacity) and the rabbit warren of corridors that they needed to negotiate to get above, it was not long enough.
Like Seumas says, there was a large element of personal responsibility involved in chances of survival and because of the deeper position of most Third Class areas and the complicated route to get to the upper decks, that personal responsibility would have been correspondingly greater among the steerage passengers. Not fair I know, but that was how it was; the Captain and crew were not supermen who could perform miracles to save one and all so people had to try and help themselves. Some, like Zainni, Lang, Cohen and especially Latifah Baqlini with her brood did just that and survived; others, like the group Wennerstrom saw doing nothing but sitting in a circle and praying, did not and were lost.
When we consider the fact that there were not enough lifeboats for all souls on board, we have to also think of another factor. IF everything had happened exactly as the various events did BUT there
had been enough lifeboats for everyone on board, would there have been time to use them and save the lot? The answer has to be NO in my opinion. The last lifeboat to be properly launched was Collapsible D at 02:05 am and even that had to he hurriedly lowered only half full. The 2 last lifeboats, Collapsible A & B actually floated free in the flooding, the former damaged and waterlogged, the latter upside down and usable only as a raft. Under those circumstances, even if the
Titanic was carrying 20 more lifeboats, they would have been of no use.
