Mike, one very big problem was that a lot of people, passangers and some of the crew(Like stewards, stewardesses, et el) didn't beleive it was serious, and when word started to get around, a lot of people still didn't beleive it. The idea of an unsinkable ship sinking was rediculous. Even some of the officers didn't beleive it was serious at first. (See Lightollers testimony in the U.S. Senate Investigation as an example.) If some of the officers don't beleive it's serious, how do you get a fussy first class lady to give up the certain comfort, warmth and safety of the ship for the cold open lifeboat about to be set off on the North Atlantic in the middle of the night?
I have no doubt that effective communications was one of the first casualties, but as to neglect, well, the Sunday boat drill was canceled, and when the ship was going down, it was all the officers could do to find crewmen who were actually competant to man the boats. There weren't that many. I'm sure this just scratches the surface, but you get the idea. Rumor has it you're a smart guy. ;-)
Cordially,
Michael H. Standart
