Why do I keep getting negative 9/11 posts on my instagram feed?

I'm remember that awful day. Literally no words to describe it.

I'm not from the US but I had the day off that day and watched the news the whole day.

I keep getting memorial stories about the people who were on the planes and who worked in the towers.

I've been reading some negative comments about people saying the planes weren't real.

Sorry to bring this up, but what were those planes then?
