PIA have been banned internationally before and following their own government's highlighting of forged licences and other problems I would be surprised if this is not being currently considered. As far as learning points go, this crew appear to have displayed a level of competence of someone playing flight simulator for the first time. So I am not sure how relevant it is. The tragedy is that they were so close to the airport in the final moments. Had they lowered the gear later they might just have made it. But given the rest of their performance it is hardly surprising that they did not.
