An Ethiopian Airlines planelanded at an airport that is still under construction in Zambia, "by mistake," a government official and the carrier announced on Monday.

The cargo plane touched down on Sunday at the not-yet-finished airport in Zambia's northernCopperbelt province, which is currently served by the Simon Mwansa Kapwepwe International Airport, some15 kilometers(9 miles) away.

Landing glitch

"When he was about to land he was communicating with the radar, and they told him: 'We can't see you,'" the Transport Ministry's permanent secretary, Misheck Lungu, told the news agency AFP. "So he used his sight as he had no control and landed at an airport still under construction."

Lungu added that no damage had been incurredand said investigators would be releasinga "comprehensive report."

Thoughthere is nomention of the incident on its Twitter page, Ethiopian Airlines confirmed that the episode had taken placeand said an investigation, in cooperation with Zambian authorities, was already underway.

Pandemic delays airport opening

Zambia is Africa's second-largest copper producer, with the majorityof the mineral locatedin the Copperbelt region.

The Chinese-built airport in the Copperbelt was supposed to open inmid-2020, but was delayed by the COVID-19pandemic.

Once finished,the $397 million (€336 million)airportwill have a greater carrying capacity than its predecessor, with upgraded amenities and 3,500 meters(3,827 yards) of runway.

Cargo flights have helpedEthiopian Airlines remain financially viable during the pandemic, with Africa's largest carrier using dozens of passenger planes as freight transporters. (AFP)
