I agree with a lot of what Arun has to say. While I do think that loading lifeboats more fully and allowing men in when there was space could have helped with women reluctant to leave husbands or in situations like Edith Evans it would not have helped in all situations. If passengers did not want to come on deck or got lost making their way there then there was little that could be done. Could a greater number have been saved? Possibly. But too many factors existed to keep all from being able to make it outside of the most perfect of circumstances.
