The PIA pilots totally fucked up the approach, missed that they were very high late in the approach, dive bombed down to the runway at the last minute instead of going around. CRM issues -- the senior pilot plausibly couldn't actually fly (he had a history of bad approaches with unsafe descents) and the first officer failed to raise major problems or push back at all on unsafe decisions. When they first touched down gear up, they had dual stick inputs (one pilot was pushing down, one was pulling up) -- this is a huge no no. Communication in the cockpit was awful. Just lots of awful.

After the incident, PIA pilots were audited and determined like 1/3 had fake or suspicious pilot licenses(!!!). Lots of paying other people to pass tests for you. Internationally, PIA has been banned from landing by like all first world countries.
