A Pakistan International Airline (PIA) flight, scheduled to go to Islamabad from Karachi, landed back at its departure airport on experiencing a technical fault on Monday. The flight was already 20 minutes late and landed back 15 minutes after its departure.Earlier this month, a PIA flight’s departure was delayed for two hours after a bomb threat. The flight, going from Lahore to Karachi, was given the go-ahead for take-off following a thorough search of the aircraft by the Bomb Disposal Squad. Another PIA flight skidded off the runway at Lahore airport last month due to heavy rain. It was carrying 42 passengers and four crew members who all remained safe in the incident.
