I was a Learjet captain flying checks for the Federal Reserve Bank. I had just gone to sleep after flying the night shift. My parents called, waking me up and alerting me to the horrible live coverage. I was dutied to fly 9/11 night, with special essential government approval, but it was impossible to get fuel. I did, however, fly on 9/12 with only a few other aircraft, mainly military. It was a solemn feeling, hearing the silence on the radio. We were regularly identified by military aircraft visually. I remember the millions of people below who had their lives disrupted, yet the tranquility above. I said prayers at 41,000 ft. that night for all the suffering.
