Where were you during 9/11? What has changed in 20 years?

I was in my 2nd AIT, reclassed, at Ft. Eustis VA.  I was 2 signatures away from clearing post, and we got the word that we were on lockdown.  After forming up in our barracks' Day Room, its where we found out why we were on lockdown and watched, on tv, the second plane hitting the second tower, completely missed the first one, but thanks to the news, was able to watch the recap footage.  As you have stated, something I think I will never forget where I was, what I was doing when this happened.

Just returned from a 6 month deployment in a limited version of Drydock. Was suppose to attend a retirement that morning. Ended up manning a 50 cal for then next 3 days, was one of 5 people trained as a gun captain on the ship

Tech School @ Keesler AFB, MS. We didn't know what happened until 1600 that afternoon. All we knew was that we went into FPCON Delta.

I was stationed at Fort Bragg as a company commander of the hospital's Medical Hold/Student company.  We watched the events unfold in the dayroom and everyone was speechless.  The base was on lockdown with extremely long lines of people trying to get onto post on 12 Sep.  I remember seeing the MP's driving around post and manning the gunner turret.  They had a several block radius of the garrison HQ barricaded off.  Definitely a surreal, numb feeling.

I was the Incoming Staff Duty NCO for the 63d Signal BN at Fort Gordon.  I was watching either CNN or Fox News, as they were the only channels authorized after 6 am, but When the news first broke about the first plane, I informed the CSM about what appeared to be a tragic accident, and went back to the Staff Duty Desk, which was just outside of my S-1 Office.  When I watched and saw the second plane aim for and hit the South Tower, I ran down, and went directly into the BN Commanders Office, interrupting him in a meeting with some of the Company Commanders and I informed him that he needs to see what is going on, and I turned his TV on, and he saw what was happening, and he then ordered me to get all units on alert, full battle rattle and to recall everyone who was on leave.  Then everything around Fort Gordon went crazy, as we were then ordered by the BN Commander to get our family members away from potential "soft targets", (I.e. schools or other places that the terrorists could target a plane to cause mass casualties.) and on post, for those of us who lived on post.  Those who lived off post had things exponentially worse, as it took on average 6 to 8 hours to get on post.  So being the first line supervisor in the S-1, I ended up having to do the work for those who lived off post,  and it was not until the 14th before I got to go home for some time off, as we were in 24 hour operations.  That lasted for about two weeks, as then we were informed our sister battalion was being deployed is support of the "new" NORTHCOM in D.C., PA and NYC.  Talking to some of my friends who are WWII vets, that was exactly like Pearl Harbor was for them.  

My son was born in June of that year. I had decided to leave Active Duty and return to the civilian life. I ETS'd on 25 Aug 2001. I was working in my civilian job as a truck driver/heavy equipment operator at a job site in Woodstock, GA. I was standing in the bed of the truck, hand-loading construction debris, when a fellow driver came by and asked if I had been listening to the radio. That's when I first heard about the first plane hitting the tower. My first thoughts went out to my brethren still at Ft. Campbell and how this was going to affect them. Two days later, my Reserve unit was calling me, telling me I needed to report in as soon as possible, two weeks before my first scheduled drill.

My take was why are there aircraft over restricted space?    It looked all wrong to me and I was in Tampa when this happened.

I was on my way to a Safety Standown for my P3 squadron,  I heard reports on the radio and it seemed like no one knew what was going on.  When I got to the hall the standown was being held, all the TV's were on and everyone was watching the news.  We were due to deploy in 3 months to Diego Garcia and we all knew that everything had changed.  I spent the next few weeks numb as I learned a few days later that I lost a friend in Tower 1.
