I was independently developing an application for several months leading up to 9/11. It was the only application scheduled for completion during that several month time period. I was working 7 days a week, at least 12 hours a day. Then 9/11 came around, and they kept us at work saying, "what's the big deal?" I continued working.
During the week after 9/11 the company employees were in a panic. The CFO assured us our jobs are safe and there is no truth to the rumors.
By the time I finished testing my app and began to write docs for it, the CTO sternly asked me EVERY 30 MINUTES if I was done yet. "Are you done yet? Are you done yet?" I was proud of my work and told him I'll let him know the minute the docs are complete. He persisted asking me every 30 minutes.
Finally I told him it's complete. He immediately got up from his desk which was across from mine and walked out of the room. Ten minutes later I was called into the CFO's office and became the first employee of the company to be "laid off", and was given no severance. That was the beginning of the end, and the company soon folded during the post 9/11 IT slump.
