I want to know the answer to the following question:
What is the airport in Namibia?
All the background I'm provided with is that "According to The Namibia Tourism Exit Survey, which was produced by the Millennium Challenge Corporation for the Namibian Directorate of Tourism, 56% of all tourists visiting Namibia during the time period, 2012 - 2013, visited Windhoek.". Is that enough to answer the question?
