True vilas, and very systematic. Only half of the story though, the less important one. It is not right they did not have a workable plan to a known hazard, what's wrong is how the situation was allowed to unfold.
The A/C left 1700 ft 2 NM before the G/S intercept point and dived with 2700 fpm. Eventually becoming stabilized with -2000 fpm' for 40 seconds until approx 400 ft AGL. Then an adjustment was made reducing to -300 fpm for another 40 seconds, still descending to surface.
Apart from the preparation, assessment and mitigation that śhould have been in place, a completely different toolbox of skills was not present to stop the developing situation. If the report and corrective actions are only limited to what you describe - stage 1 - of what happened, it would be a very sad state of affairs. A missed opportunity as well, let's wait and see.
