President of Pakistan Air Lines Pilots Association (PALPA), Captain Sohail Baloch on Wednesday said Margalla Hills plane crash may be attributed to pilots fatigue. The pilot may be suffering from accumulated fatigue because they are not given adequate leaves, he told a private news channel. Captain Sohail Baloch said the route was not a no-fly zone, as speculated. The plane exceeded the safety distance due to bad weather. He said this decision was, again, taken by the pilot who could not determine appropriate landing route and added the ISL systems access ends a little before Islamabad and the pilot had to resort to visual queues for landing. There could be other reasons to the crash, which will only be uncovered after completion of investigation, he added.
