this (and Curt Olson's) make it seem quite worthwhile!

I'd never been able to find any claims on accuracy of FlightGear's FDMs;
not from the FG website, the FAQs nor trawling the devel-list archives.
And yet, here it is!

Surely someone ought at least to mention this level of FDM fidelity on
the FAQ? It could only help increase FG's street-cred.

development cycle, seeing what he could get from published diagrams, and
what he had to estimate. It will be even more interesting if/when he can
