Anecdotally, I don't know that piloting a Black Hawk is any harder or easier based on sex. I imagine if you are very short or very tall that might be impactful. I'm not a helicopter expert though, so no idea.
Unless there is some direct linkage saying she was a pilot and got that job ahead of a more qualified person because of her sex, it's pretty difficult to yell DEI on this particular incident. Light research shows she had many hours, and the bulk of those hours specifically in a black hawk. All the failures Rock states as fact are coming I think from daily beast and the final NTSB report comes out in 2026! I think I'll cool my jets (haha) on this until there is substantive actual data, rather than echo chamber Trump saying she's a DEI hire. I like Trump, he can be wrong and I can still like him.
