A Pakistani Boeing 737 cargo plane bound for Karachi has gone missing after losing contact with air traffic controllers. The aircraft, which was carrying five crew members, disappeared from radar after reporting a fault with its navigation system.
Flight data and radar systems indicated that the aircraft descended rapidly and plunged vertically before communication with the crew was lost. The plane went missing over the Arabian Sea.
Pakistan's Navy and civilian authorities have expanded the search for the cargo plane, which is feared to have crashed.
