Do you have a source for this? It's not on the transcript I've seen; and David MacLaine whose words are recorded on that transcript never told me about the words you quote. (MacClaine was flying opposite direction traffic at 15,000 and saw TWA 800 explode from a distance of about ten miles. I've spoken to him on several occasions about TWA 800, once for more than an hour. He did, in fact, quote words he said that night to ATC, before there was any public release of the tape or transcript so I suspect it might have come up. ) I think your quote is bogus.
In case you are not aware of my own thoughts about TWA 800, you might read TWA 800 "It wasn't terrorists. It couldn't have been."

Of you Google the quote that should help. Here's a direct link to where I got the quote from:
