What about airplane designers (both in industry and science), aircraft systems designers, scientists designing the man-machine interface (cockpit), regulators, trainers, writers of training manuals, air traffic controllers, and all of those folks, who contribute to and build the foundations, that airline pilots rely on?
If those folks are excluded from those discussions, quite a few important aspects could not be handled, and both those aviation professionals as well as the airline pilots can not benefit from such discussions.
