The airplane with Pope Benedict XVI onboard arrives at the international airport in Yaounde March 17, 2009. Pope Benedict arrived in Africa on Tuesday on his first trip to the continent as pontiff, seeking support for the continent during the world economic crisis and hoping to encourage peace and help tackle corruption. The Pope began his two-nation tour in Cameroon, where workers whitewashed walls, and rubble-strewn pavements were swept and cleared of street hawkers in last-minute preparations.
