This suggests different data sources but referring to the same point in time, subject to the nature of 'initial findings'. It is remarkable to think that the Go Pro in cockpit camera survived.
To you bu$$ers drinking all my coffee, an ironic sort of "thank you"
Keep your mitts of the ground stuff - that's for the Boss and visitors only. And use the Long Life ...
Deef's - thanks mate - all input welcome and your jottings are duly archived
My overarching point remains.
Rule 1 - stay out of trouble
Rule 2 - when in trouble, depart the trouble quickly
Because for sure 100kt at 2600' is a compromised top-of-loop kinda' position in an aircraft that needs perhaps 3500' to recover through the vertical and regain S & L flight as per the DA by 500'.
As m'honorable gentleman BEag's has suggested there are possible reasons for less thrust than might have been thought [although speed / throttle setting might have been an old fashioned check on that in the run in]
Lets leave it that the risk of a fully developed stall and its secondary effect means that your manoeuvring options are limited.
Back to the whiteboard people, focus now:
Talk me through your recovery from this assumed 100kt/2600' agl/Inverted 'unusual position'.
Here's AH's office for the day [and here's a glass to his eventual recovery in hospital and to his family and support network]
This is the Gatport Airwick Hunter

For those of you who have not seen the wide range of public imagery
These are some images I exposed, one of which showing the departure from the inverted and one shortly before a high rate of sink developed

The fact remains, and it is sobering in its wake up call for us all, that it all happened so very quickly. Aviation at low level remains somewhat unforgiving when things start to unravel.
