None that I'm aware of. But as I'm sure you are aware, pilots are trained that in the event of an emergency, making a radio broadcast is one of your last priorities. It would be very odd if someone made a radio call about witnessing an explosion the second TWA 800 blew up.
Another of your inanities.
Pilots are trained that in the event of an emergency IN THEIR OWN PLANE, that making a radio broadcast is a low priority. McClaine wasn't declaring an emergency, he was observing one. BTW there are plenty of gaps according to the transcript for him to have come in earlier. (You supposedly know how this works.)
You still didn't tell us where the 31:12 time comes from, yet you cited it, and apparently think it's important. Did you just make it up?
