The 20th anniversary of Sept 11 is sure to bring up a lot of memories and emotions. What has changed and what have we learned?

I grew up in New York and I lost two friends in the collapse of the World Trade Center. And I was in the Pentagon that morning... grateful to still be here

I was in Philadelphia on that morning. I had fallen asleep in the hotel and woke up to watch the second plane fly into the second tower. The trainer assigned to my install was in the air flying in from FL, her flight was diverted to SC. Driving to the work site was surreal, the streets of City Center were empty. A lot has changed and not in a good way. What I've learned is that career politicians and bureaucrats are not benevolent.

After the 9/11 attack, the nation was the brotherhood and sisterhood of Americans, no matter what color or political persuasion. We were united against our enemies. Fast forward 20 years and we have surrendered to the Taliban and left Afghanistan in disgrace, plus we have surrendered our country to the marxists and criminals. Not really a stellar 20 years that we should be proud of. I'm ashamed to face those murdered in the attack and have to answer why we who survived the attack let it come to this.

One thing has become abundantly clear...the American people have a woefully short attention span. We've also learned career politicians are NOT looking out for the Nation's best interests unless it happens to personally benefit themselves.

It appears, the information from the 9/11 commission verifies the flight school info on some of the warriors for Su’en wanted to learn how to fly jets and not too concerned with landing. Where was the FBI Leadership on this info? Sitting on it?
This event was Islamic terrorism and it appears many at the King Farouk Mosque supported the attack as fitting for the country they lived in.
I wonder who has come through the wide open US southern border these last 8 months?
Don’t worry, I’m off to complete some online compassion and sensitivity training modules.

God bless America. Here in the UK, we share your thoughts and prayers at your losses from 9/11.

Being a flight attendant for one of the two airlines used for the mass murders and terrorism on our country, aviation has changed tremendously when it comes to security. There are things I can’t post, but my job has changed in the way we perceive the work environment and passenger encounters. Heightened awareness is a small part. The naïve innocence of the friendly skies are a thing of the past, we are constantly assessing our surroundings on every flight, everyday for the past 20 years. And that level of intense observation causes us to think about 9/11 everyday, the events from that day never leave crewmembers. Personally, my friends were working on one of the jets, and I continue to grieve, it’s s painful reminder to see their faces each time I go to work.

It sounds odd reading these post, but I was Six years old when the attack happened. I watched the plane hit the second tower. Nobody thought the impact that would have on a Six year old. I was living in my Hometown in Upstate NY, Six or so hours from the city.

As for Lessons learned we have learned things. Any new experience, any new event is a lesson to be taught. The attack showed us the flaw in American Pride, we were touchable, we could be hit at home. We learned that we needed to increase security on the home front and over seas. We learned Americans can put their differences aside and unite as a single country. Yes we still have to continue to grow and learn but as long as we do that, as long as we try and learn from what happened and grow from it; we can be better.

History is made of lessons and mistakes we have made as species. Its only from learning from those mistakes we can be better. We allowed our hubris to get the best of us. We said it won't happen again, but they hit the trade center not once but twice. After the bombings in the parking garage we should have known. We did nothing because the idealism that we can't be hurt, we can't be hit. It is sad that it takes a major tragedy to really effect change. We have learned from it; proactive not reactive.

I was 52 years old and in business for myself, was discharged USMC Vet and called the Marine Corps to re up , they told me to do some community work , which I did but I really would have reupped if they wanted to take me !

I was on leave with my ex husband. We were only 3 1/2 hours from our duty post. His mom called and said we were under attack. We looked at each other and said we’re going to war. By 2002 I had started my first deployment. It’s saddening to see Afghanistan fall to the taliban the way it did. It just so different..
