Pakistan’s chequered aviation safety record
Pakistan has a chequered aviation safety record, including a number of airliner crashes.
PIA, one of the world's leading airlines until the 1970s, now suffers from a sinking reputation due to frequent cancellations, delays and financial troubles. It has been involved in numerous controversies over the years, including the jailing of a drunk pilot in Britain in 2013.
In 2010, an aircraft operated by private airline Airblue crashed near Islamabad, killing all 152 people on board - the deadliest air disaster in Pakistani history.
In 2012, a Boeing 737-200 operated by Pakistan's Bhoja Air crashed in bad weather on its approach to land in Rawalpindi, killing all 121 passengers and six crew.
And in 2016, a Pakistan International Airlines plane burst into flames while travelling from northern Pakistan to Islamabad, killing 47 people.
