If you really are from Islamabad, quite a few possible scenarios come to mind immediatly -
try problems while under non radar HF airspace with congested freq (mumbay), high terrain with pressurization and/or engine problems (northern Pakistan, Afghanistan) - how about any political issues to be observed in your area - we used to have lots of soldiers on board when flying to Kuwait, so they gave us a scenario with an engine failure overhead Bagdad (A330) with the threat of antiaircraft fire in Iraq (no fly below 25000') and the obvious diversion to Iran not being too smart of an idea...
Just be creative
