Maryam Masood and Erum Masood two sisters working as pilots for Pakistan International Airlines or PIA have become the first such pair to fly concurrently the Boeing 777 aircraft, according to reports. According to Pakistan International Airlines spokesperson Danyal Gilani, Maryam Masood and Erum Masood had been flying different planes and it was only recently that the duo got the chance to share the same cockpit. Reports said that this is an unparalleled feat in Pakistan International Airlines. He said that there is no known record of two real sisters having flown the same weight category aircraft concurrently. Recently, one of the sisters, Erum Masood, was promoted and cleared to fly a Boeing-777, which resulted in the happy coincidence of both sisters flying a plane together. Maryam Masood and Erum Masood are both first officers who usually fly different aircrafts; Mr Gilani is reported to have said. They are second only to the pilot, who usually has longer experience. This is a good news from Pakistan International Airlines, which has been running in losses for years and is struggling to improve its performance.
