They don't have to actually be a "DEI hire" in the sense of being incompetent, just perceived as potentially such. i.e. they must belong to some demographic that is generally perceived as receiving preferential hiring due to affirmative action type policies. e.g. women, blacks, native Americans, etc. (Asians don't count since they're generally discriminated against, not towards. Veterans don't count because they're not part of the culture war about DEI, even though they do get preferential treatment.)
The mistake needs to be in the context of the skill of flying a plane for their job. A car crash doesn't count, even if they were driving to their job at the airport. Running the plane into something while on the ground would count. Crashing a personal plane they were flying for fun does not count. If it's an intentional murder/suicide like flight 9525, that counts too.
Anyone with normal access to the controls counts as a "pilot". If it's unknown who made a specific error, default assumption is the captain.
