Not a accident , The planes were hijaked by 19 men. And they got into the cockpit of the plane , and stabbed and killed and MACED the pilots . and ran them into the twin towers. because we threw blacklash at Muslims . And the people who hijacked them were Muslim.so they hijacked us because they hated us and went after the twin towers and when they burned down they ran into the pentagon where the 5 branches are. And after they tried to go for either the White House or capital were unsure because the people in the plane fought the hijackers and ended up crashing in Pennsylvania.
