Everyone has moments when the need to get the job done or need to get home impinges on their decision making and there are few pilots who haven't taken a chance during their flying careers - you won't ever prevent that - but at least you can arm them with the training and skills to get themselves out of the poo when it goes wrong.
This case, along with the two 139 crashes mentioned earlier are exactly a case of poor decision making coupled to a lack of training to recover when those poor decisions overtook them.
In all 3 cases, basic instrument flying skills would have saved them IF they had been applied.
Are you saying that these pilots were not trained in how to deal with IIMC?,...because even a lowly Robby pilot like myself has been trained in basic instrument flying skills, unusual attitude recovery, and the idea that climbing is a better recovery technique than the good old 180.
Thing is, once you start down that path of irrational decision making, the thought to simply climb out of it may not even cross your mind,...despite you being trained to do so. At least that's how it was for me.
