Flying has always attracted chancers and characters to Africa. Wilbur Smith’s father so loved aviation he named his son to honour the Wright Brothers. ‘I am forever grateful he didn’t go for Orville,’ the Zambian-born author once confided. Smith father and son may well have approved of Giles Foden’s romping novel, which has African bush pilots at its core, and a style not dissimilar to that of an airport thriller.
