I agree that we got (with my comments in [brackets]):
- sworn testimonies by highly respectable & trained people, [that I never saw quoted in extenso (if you have a reference, I'm interested), except for one ATC who said IIRC (TV show) he was not looking towards Concorde when she began her T/O roll];
- sworn testimonies by certainly also respectable people, [but not trained in any way, for exemple the foreman seen in the TV parallel inquiries];
- all those people were situated, at the time of the accident, relatively far from the aircraft [making it difficult to jaudge distances];
- the "step" on the runway that could have played a role "before the strip" [but I can't remember any evidence or even precise/factual hypothesis about that].
I think you can have some answers to your questions about references in the minutes of the trial:
