Look at this:
The date of the attack: 9/11 - 9 + 1 + 1 = 11

September 11th is the 254th day of the year: 2 + 5 + 4 = 11

After September 11th there are 111 days left to the end of the year.

119 is the area code to Iraq/Iran. 1 + 1 + 9 = 11

Twin Towers - standing side by side, looks like the number 11

The first plane to hit the towers was Flight 11
