Titanic breaking in half

The Titanic breaking in half was a key event during the 2 hours and 40 minutes of the RMS Titanic sinking. Many survivors (such as Officer Lighttoller) did not recall a torn-up in the deck.

1:39 am or 2:17 am
Some survivors, such as Jack Thayer, recall a rip at like 1:30 or 1:39 am, and that the bow rose itself up. However, many people today believe it tore apart at 2:17 or 2:18.

Another issue is the fact that if the Titanic broke in center of the third and fourth funnel. After all, the 1997 movie shows this. But, that same director pointed out that it broke in half in 2012.

Bow
Another one is the fact that many survivors recall the bow rose up for a short while. This is not believed to happen to many today.
