FSX/P3D. ASDG / African Scenery Design Group has set out to develop the famous South African O.R Tambo international airport and so far, all the previews the team has presented since mid last year has shown great promise. The group has uploaded heaps of new screenshots today. The scenery will be published by Aerosoft. Just like with Istanbul Ataturk, Johannesburg is one of those airports people have been begging to get for years. I will continue to follow development closely. Here are just a few of the new development previews.
