ChristiaanJ,
Maybe.
I'll take a closer look again. There are some things I cannot quite reconcile.
I cannot even see that the pitch curve as drawn in alph2z's post bears any more than superficial resemblance to the plot from the report.
It is extremely smoothed, the plot in the report has many more bends, which are significant.
If the source really were the plots in the report, I doubt that anything meaningful can be gained by creating smoothed curves from them. With high-fidelity data it would obviously be possible to determine AoA from pitch, speed and altitude, but I doubt that the data as represented in the report's plots is accurate enough for a meaningful analysis.
