That's an odd comment. When someone like Stan Hall writes about
stability, control, and structures, I listen. Carefully.

Even the best pilots may have accidents, and even a well known engineer
may write obvious stupidities. Obviously Stan Hall did make statements
that are completely false. He admits himself that he never flew an open
class glider, and that should have led him to be more prudent in his
analysis.


I think the bottom line in his analysis is very clear. Open Class
performance comes with risks that need to be completely understood AND
there are flight regimes where the margin between recovery and disaster
is very, very thin.

*That* is right. As it has already been discussed here, that the load
factor admissible with airbrakes out is much lower than without
airbrakes. This is obviously not easy when recovering from a spin not to
apply too much g-factor, especially above VNE or near the ground, but it
may save your live !
