The PIA flight (PK-270) was scheduled to land at 2.40 PM but while making an approach to touch down, the pilots could not align the Boeing 737 plane with the instrument landing system (ILS) which guides aircraft to land safely, airport sources said.
The Pakistan airlines was not available for comments.
Failing to establish connection with the ILS, the air traffic control officer (ATCO) gave the headings (direction) of the airport to the pilot but he once again failed.
The pilot then went for "go-around", but failed to land once again.
With so many failed attempts, the pilot then decided to return to Lahore, the sources said, adding it seemed there was navigational problem with the aircraft.
The sources said no flight plan has been filed by the airline for now, which means the flight is unlikely to come back today.
