I really would love to see it redone with all of the knowledge we now have today.
Same here and I don't see why not. 28 years is a very long time.
Getting back to the subject of the OP, I believe that the reason as to why poor Loraine Allison did not get into any lifeboat is disturbingly simple. From witnesses like Gracie and Peuchen we know that Bess and Loraine were actually sitting in Lifeboat #6 before the former got off with the girl in the last moment. It is not too hard to guess that Bess did so when she realized that her husband
Hudson Allison was not going to be allowed into the lifeboat with her. After that, the family very likely remained on the port side with Hudson vainly trying to persuade Bess to get into another boat but with the woman standing her ground. Even of they had moved aft on the port side, things were not much different and Wilde, who appeared to be there on a sort of supervisory capacity while Lifeboats #16, #14 and #12 were launched, was not allowing men in even if there was room. Bess and Hudson probably did not even consider letting another adult take Loraine into a boat, especially if the little girl - as is very likely - was by then clinging to her mother and crying.
The question of why the 3 of them did not cross over to the starboard side where all of them almost certainly would have found places in a lifeboat is harder to answer. The most obvious one could be that
they did not realize that Murdoch and
Moody were allowing men into boats if there was room (note how the Caldwells, Sylvia and Albert, were able to hand in baby Alden first and then follow him into Lifeboat #13 soon after) and when they did, it was too late. Also, far more other
First Class passengers, were congregating on the port side, where the Captain was also there for the most part. The Allisons might just have felt more comfortable remaining with their 'contemporaries' in a more familiar atmosphere.
Finally, its probably a bit unfair but from what Alice Cleaver said,
Hudson Allison does not come across as someone who was very decisive in a difficult situation such as the one that they found themselves that night. Between that at Bess' adamancy, poor Loraine paid the ultimate price.
