4. Lifeboats Not Full
Not only were there not enough lifeboats to save everyone on board, most of the lifeboats that were launched off the Titanic were not filled to capacity.
For instance, the first lifeboat to launch, Lifeboat 7 from the starboard side) only carried 24 people, despite having a capacity of 65 (two additional people later transferred to Lifeboat 7 from Lifeboat 5).
However, it was Lifeboat 1 that carried the fewest people - only seven crew and five passengers (a total of 12 people) despite having a capacity for 40.
