Lack of training, maintenance likely led to Taliban pilot crashing Black Hawk, military aviator...

well let's hope they keep crashing and wreaking everything Biden left behind

I have my doubts that there is credible training

Blackhawks were only recently introduced to the Afghan Air Force well after I left in 2014. Up until that point MX training centered a lot on Soviet era platforms (MI-17) using Czech advisor technical knowledge and US advisor doctrine. Bringing in the Blackhawks essentially changed the whole approach, and likely introduced a lot of positives for the US advisors, but ultimately significant challenges in reworking the training. When we left, we left a huge vacuum in air power MX, combat support, and air control, which is what absolutely led to the Taliban taking over so easily. On top of that, most of the Afghan pilots (who were all very well educated compared to most of the ANA and AAF) either left Afghanistan or were captured and potentially killed. I would imagine there are very few competent pilots and maintenance experts (if any) capable of caring for the Blackhawk.
