Authorities have located the black box of the cargo plane that skidded off the runway into the sea at the Hong Kong International Airport on Monday, killing two security staff members, according to an airport official.

Steven Yiu Siu-chung, the Airport Authority's executive director for airport operations, said in a radio interview on Tuesday that experts have confirmed that the flight recorder is located at the rear of the Boeing 747 aircraft, local newspaper Ming Pao reported.

Yiu also said that a crane would be required to lift the wreckage and retrieve the black box and this would be done once tropical cyclone Fengshen moves away from Hong Kong and typhoon warning signals are lifted, the report added.

The cargo plane, operated by Turkiye’s AirACT, apparently lost control after landing at 3:53 am on Monday and veered off the airport’s north runway.

It struck a vehicle with two airport security staff members who were patrolling the perimeter road outside the runway zone. Both the cargo plane and the patrol car plunged into the sea.

Fire services rescued the four cargo plane crew members to safety but the two security staff members died in the incident.
