This is a real court case with people's lives and repurations on the line - and the guy testifying obviously doesn't know what he is talking about.
Some expert.
With respect, I have been aquainted with Mr Mac Gillivray some time ago and he is most qualified for the "expert witness" role.
Aside from having a qualification in AEng, he is a qualified Test Pilot who worked extensively on the delevopment and certification of the Nomad (no jokes thanks!).
