Since George S and Kallstrom talked about TWA 800 on 9/11, the first guess is they spoke the truth off the top of their heads, without talking points. Note there hasn't been a fleet of talking heads echoing what they said.
A darker thought is they knew 9/11 was coming and saw an opportunity to protect the Navy's reputation. Again, since no one has echoed, they seem to be on their own.
Interesting that George S used "bombing".
Hey, thanks. My take also, that in the heat of the current situation they inadvertently told some truth. I'm weighing "bombing" vs. 'missile attack' or 'shoot-down'. Sometimes I myself have mentally used 'bombing' as a shorthand for 'missile attack' and wonder if George does too.
