I'm listening to ATC for education. I'm not confident in my ability to understand it correctly. That's why I qualified my level of certainty.
FWIW, the KBOS incident I saw didn't seem to be ATC either, if it was actually what I thought it was. It does seem like either of them may have been caught earlier if there had been more ATCs on staff or if they weren't as stressed or sleep deprived.
