It's very rare for an aircraft to land at the wrong airport, but over the Easter weekend it almost happened twice.
The first incident involved an Ethiopian Airlines cargo flight from Addis Ababa, Ethiopia to Ndola, Zambia.
According to reports, instead of landing at its intended destination at Simon Mwansa Kapwepwe Airport, the plane landed at Copperbelt International Airport which is still under construction.
The embarrassment for the pilots may have been compounded by the audience of hundreds of construction workers whose work was interrupted by the unexpected arrival.
Just hours later on Sunday (local time), another Ethiopian Airlines plane almost made the same mistake.
Passenger service ET871 was flying the same route Addis Ababa to Ndola when crews realised they were about to land at the wrong airport. They undertook a last minute go-around before heading to the correct airport.
While a full investigation is underway, pilots who have spoken about the incidents online say a possible factor could be that the runways of both airports run at almost identical angles and are closely aligned when approaching from a distance, and that the Copperbelt airport is more in line with what pilots would be expecting from a city's major airport due to its size.
