An Ethiopian Airlines plane landed 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 northern Copperbelt province, which is currently served by the Simon Mwansa Kapwepwe International Airport, some 15 kilometers (9 miles) away.

The transport ministry’s permanent secretary Misheck Lungu said the pilot had landed at the future Copperbelt International Airport by error.

“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, said.

According to Lungu, the pilot used his sight as he had no control and landed at an airport still under construction.

Lungu added that no damage had been incurred and said investigators would be releasing a “comprehensive report.”

Though there is no mention of the incident on its Twitter page, Ethiopian Airlines confirmed that the episode had taken place and said an investigation, in cooperation with Zambian authorities, was already underway.
