9/11 is a really depressing day because the twin towers fell that day. That day i was in school and I was in first grade so I had no idea what was going on. I also remember being picked up early from school, and I heard something about buildings falling down in NYC, but other than that I didn't know what had happened. Then in later years I found out that in total 4 planes were hijacked, but only two aimed for the twin towers, the other went to DC, and the fourth one went to PA. About 2,976 people died that day .I think that we are still at war with Afghanistan and Iraq because of the 9/11 attacks. They used our planes to achieve their plans.
