I didn't mention it cuz I figured if they're monitoring calls for it then they're damn sure monitoring posts for it and I didn't want to end up on a list. But what the hell, I'd rather learn more about what this is really all about. And that's the thing: the word wasn't even that crazy, unless you're on line at an airport (apparently) which I wasn't.
The word was "bomb".
(...Now that I think about it, I was at a train station. Not a major one though, doubt if that's related.)
It was not a coincidence. I created an account just to respond because I've been waiting years to have my experience... "validated".
The same exact thing has happened during phone conversations I've had except with a different word. And I first noticed it years ago but it was post-9/11. When it happened I thought the phone call dropped by accident. I called back and picked up where I left off telling the same story. At the same word the call dropped again. I called back again and said "uhh, that was weird. Did you notice it cut off again when I said _______?" And the call dropped once more. At that point there was no plausible way it was a coincidence. The next time I called, I decided not to test it again.
I've been looking out ever since for some mention of this somewhere. Never saw one until now.
