Squawk 7700: Air New Zealand plane lands safely after ‘minor incident’

Air New Zealand aircraft ZK-OKP has landed at Heathrow Airport in London after transmitting an emergency code while over the Atlantic Ocean.

The Boeing 777-300 aircraft was operating flight NZ2 to London from Auckland via Los Angeles.

A 7700 squawk code was sent from the aircraft which indicates to controllers on the ground that the pilots are dealing with an emergency situation.

Twitter user, Jon Wornham who works in air traffic control tweeted that the emergency may have been due to an hydraulic issue with the aircraft.

Website Heathrowcam.net captured this image of ZK-OKP moments before it touched down.

Air New Zealand has said NZ2 landed following a minor incident, some loss of hydraulic pressure. No emergency was declared.
