Pakistan Int'l Airlines Chairman resigns after plane crash
Pakistan International Airlines (PIA) Chairman Azam Saigol has resigned, citing personal reasons, days after its plane crashed killing all 47 people on board. PIA had grounded its fleet of 10 ATR planes after Pakistan's Civil Aviation Authority decided to conduct "shakedown tests" of the carrier's entire fleet. The aircraft had suffered engine problems after takeoff, which led to its crash.
