The goal should be to hire the best team for the use case, regardless of gender/race/culture/background.

A million monkeys will never equal a single Einstein.

Just like people are judged by a jury of their peers, planes should be designed by your peers.

We should just get a representative sample of the population and give them equal say in the design of the plane, engines, etc.
