Nittany Pirate,
Still difficult to discuss.. I worked in Building 1, 59th Street Floor, and had left working in Manhattan a couple years after the 1994 garage level attack, transitioning into the Tech field for Channel Security and Private IP out of Basking Ridge NJ. I frequently visited former co workers, and clients at WTC 1, 4, 5, and 7 post my career change.
I was last in building 1 on September 10th 2001 with a CTO friend and his peers, discussing their IT needs on a 70th level floor. That friend had home issues on the morning of the 11th, and didn't get near the office until after Building 1 was hit, and before Building 2 was hit. He was thankfully told not to enter, and wait for clearance that of course never came, except for the brave first responders sent in after Building 2 was hit.
His peers were all in the office, and told to stay put. They chose to not listen and take the stairs down.
My former employers staff on floor 1 59th floor, which was well under the plane level, all evacuated safely with the exception of one who was in a meeting on a 90th level floor.
May God continue to bless his soul.
