[1] Reason of the Titanic hit the iceberg

I think everyone sure knows what is Titanic.The movie was famous since 90's and the Titanic's story was originated in 1910 British.This was a true story and the ship is the largest ship on that time.

Negligence of the captain

Reason of the Titanic hit the iceberg,in my opinion,
I think is the negligence of the captain.
Edward Smith who is the captain of RMS Titanic was fall asleep and he missed to command the right position of the ship.He didnt saw the iceberg on somewhere far and the weather was too cloudy and dark. So, the accident was happened .


Optical Illusion

In addition, I think the optical illusion should be the reason of the Titanic hit the iceberg.
It is because a thermal inversion refracts light abnormally and it can create a superior mirage.
The objects will appear higher (and therefore nearer) than they actually are before a false horizon. 
The area between the false horizon and the true one may appear as haze.
