9/11 memorials 

 An Islamist terrorist group of 19 terrorists got on 4 commercial planes and crashed two into the north and south of the twin towers. when these two planes crashed the twin towers the twin towers soon later collapsed and 2,977 people were killed. The first tower that collapsed was the second tower. I think my first memory of 9/11 was when i was in 4th grade i remember my teacher read us two books about what had happen that day. Then later on he explained what happened and showed us pictures about it.

When i learned about this i felt sad and scared.My thoughts were like why did they do that ? Why would they crash two planes into two buildings?
