"Titanic"s down angle altered fairly rapidly from zero degrees to about four and a half degrees during the first hour after the collision, but the rate at which the ship went down slowed greatly for the second hour, worsening only to about five degrees. This gave many of those aboard a false sense of hope that the ship might stay afloat long enough for them to be rescued. By 1:30, the sinking rate of the front section increased until "Titanic" reached a down angle of about ten degrees. At about 02:15, "Titanic"s angle in the water began to increase rapidly as water poured into previously unflooded parts of the ship through deck hatches, disappearing from view at 02:20.
