I worked midnight shift the night before, About the time I was going to sleep, the flights were departing their gates. My wife called and woke me up to tell me an aircraft had hit the WTC. Of course I immediately thought of a small aircraft since no one with any experience could possibly hit a building that large. I turned on CNN, saw the smoke and realized it had to be a larger aircraft. Then the second aircraft hit and I knew something was going on. I was on Delta's CIRP Team (Critical Incident Response Program) and I was sure we were going to be activated even though we didn't lose any aircraft. I spent the next few nights at work counseling younger (and some older) people who's entire world as they saw it had just fallen apart in the space of a few minutes that morning. I retired 3 months and 19 days after that but no, I haven't forgotten 9/11 or the pain of those people I talked to along with my own pain. If you don't work for an airline, it's hard to explain the loss and pain when an aircraft goes down, even when it's another carrier. The closest I can come is, for you LEOs it's like losing a brother LEO in another area. You didn't know him but you hurt for his coworkers, family and friends. It's was the same for us but multiplied by hundreds.
As dcxplant said, Godspeed to the crews, the passengers, the WTC victims, and those left behind.
