The adventure begins! A month. A fleet of gorgeous aircraft. One unforgettable adventure across Southern Africa with Josh Flowers, Chelsea Smith, their good friends Chris Lammert and Keelyn Costello, and some of us from Sling HQ. In Part 1 of Aviation101’s four-part series, the journey starts with their arrival in South Africa at Sling HQ in the south of Johannesburg, meeting the aircraft that will become their companions, ZU-TSI and ZU-DFU, and taking the first steps — or rather, first flights — into the unknown.
