I've mentioned this in other threads, but my BIL was scheduled as flight crew on United 175 on 9/11. However, several weeks prior, he'd received a speeding ticket after work one evening, on his way home from Logan airport. The officer who wrote the ticket made it pretty clear that he wouldn't be in court for the hearing if my BIL wanted to contest it, so BIL called in "sick" on 9/11 to go to court to contest the ticket so it wouldn't show on his driving record and he wouldn't have to pay the fine. Of course, he never went to court on 9/11, he want to Logan to see if there was anything he could do. He spent several years in therapy as he couldn't get over that someone died in his place, if he hadn't called in sick someone else would be alive (although he wouldn't be). Not a good headspace, but he- and we- were very, very lucky that day, that circumstances went the way they did.
