Centaurus we did put the 737-300 sim through it once.
Started at FL370 at 48T GW with full throttle, giving us M.79 B.Pole. Initiated increasing spiral dive to the left with firewalled throttles and eventual full ND ( manual-range ) trim. This had us at M1.02 (fastest speed achieved in terms of Mach) passing FL240 at -92 deg pitch.
Man we went in like a bloodey bullet!
