An Ethiopian Airlines Boeing 767-300, flight ET900 from Lagos (Nigeria) to Addis Abeba (Ethopia) with approximately 200 passengers, returned to Lagos after the air conditioning system failed and the airplane could not pressurize following the departure at 1:45pm.

Repair works did not succeed until the following Sunday late evening, the passengers still waited for their departure to Ethiopia’s capital city.
