I'm saying it may have been allowed to happen because there was nothing else in it's place during a holiday when there wasn't enough time to reach someone to fix it. It may have aired before someone caught it. I'm well aware of how Centralcasting MC works, considering I implemented the first ones in the country. One operator watching several stations on a holiday may not have been able to make the substitution in time. Big deal.
I'm sure someone over in the newsroom at WKBW likely heard there was an issue. What, you can't call over there to your contacts who likely knows what happened?
That's exactly my point as a potential reason. Someone determined there was an issue about the time it happened but there may have not been enough time to correct it by the next hit(s), assuming it aired more than once. When you have a tech running multiple stations in a hub, their eyes are bouncing around screens verifying things are all on the air. Audio consists of bouncing vertical VU meters. They're not paying attention to what some local weather person is saying about what days. WKBW is on the air, all is well.
