I observed the outcome.
As part of my job, I conduct training, not in aviation, but I understanding training. When I train someone and they go out and do it wrong, something is wrong with 1) my training delivery, 2) my training content, 3) my evaluation of the student, or 4) the student's engagement. As the trainer, even that last one is up to me and if the student isn't engaged, then I have to know that and fail to give them credit.
Bottom line, when the student performs the task correctly, the training was done right. When the student makes an error, the training was wrong.
The trained response, according to the Avweb video, is to level the airframe, slow the aircraft and execute a climb. I believe they got that from the Island Express training manual, which was probably at least edited by the pilot since he was the company check airman.
Instead, the pilot made a descending turn to the left until he contacted the ground. What I observe is 1) he did not properly execute the described training, 2) there is no way he was referencing his instruments OR he was task saturated and couldn't process what he was seeing and 3) you seem very aggressively insulted that I believe the cause of an IMC CFIT crash is bad recovery training. But the bottom line is, if the pilot had done what the Island Express training said to do then he would have recovered.
