FS2004 Scenery--Oscaldo Vieira International Airport Bissau, Guinea-Bissau. Forgotten Airport Project: FS2004 is the most complete simulator in terms of files available. However a total of 18 countries have been overlooked by addon developers. This project will close the gap. This scenery covers the international airport of Bissau which usually sees little traffic. Landclass for the city of Bissau and ships on the Atlantic have been included. By Bastian Blinten.
