There Was Enough Room for Jack
One of the questions that has plagued the minds of men since Titanic came out was why Rose didn’t share her plank with Jack? Some speculated that the plank would’ve flipped over had Jack attempted to climb aboard. However, since he didn’t try, there’d be no reason to suggest such a thing.
In fact, Jamie Hyneman and Adam Savage from Mythbusters even dedicated an episode to test several fan theories, one of which included the plank in question. It turned out that not only was there enough room for two grown men but also, they both would’ve been safe.
