Not sure of the significance of TAS but these are my rough calculations.
Just trying to picture at what point it stopped being the thing it was designed to be and turned into an object under the affect of gravity as 34 seconds after the last speed reading, it was passing FL350 at -10000fpm and possibly had no forward momentum at all (10000fpm being 107kts), just dropping vertically, wings generally level at reasonably constant pitch attitude, with engines still at 55% and no normal airflow over the stab.
It just does not make sense, but I am an engineer, not a pilot.
