Forget the regular decision height at 10:40.42, they didnīt get that one.
The crew flew down to RA 100 meters (which is below the minimum)
Therefore for them everything looks nice till 10:40:49, being still at 100 meters (RA), and time for goaround. The FO even calls it normal. And ATC gave the last information as being on glidepath.
Only one seconds later at 10:40:50 the nav calls 80 (rising terrain and high descent rate), and the FO calls goaround 1 Sekond later at 10:40:51. He even initiates a pull at the stick, which did not disconnect the autopilot, but was well recorded from the FDR.
After today's press conference, with col. Grochowski, who is a member of the Polish investigation body, it look like you may be right. He didn't want to be very specific, but said that a GA call from the PIC was followed by a confirmation by the F/O. We can hear on the transcript at 80 m height.
It still doesn't explain what went wrong next. There are some test flights to come.
In fact there were probably some yesterady, as the second Tu-154M made at least 10 GAs.
