(CNN) -- An incident originally reported as a plane accident Thursday at the Harare International Airport in Zimbabwe was a drill, British and Zimbabwean officials said.
Officials in Zimbabwe originally said the incident involved a Boeing 767 out of London.
"This was a usual drill for the period. We do this once every three years. This was for the benefit of our police personnel, security, aviation, medics, hospital -- everyone was involved," said David Chawata, chief executive of the Zimbabwe Aviation Authority. "This exercise helps the general preparedness of our facilities here."
