FSX. If you have never heard of BDO Aviation, I assume you haven't been spending any time flying the skies of Indonesia. BDO Aviation is an extremely talented group of developers from Indonesia that has developed several high quality airports for their home country. I encourage you to check out their site and products. Their latest project in development is King Abdul Aziz in Jeddah Saudi Arabia. I have been tracking another independent development of this airport and i'm still hopeful it reaches fruition. According to the team, it will be available soon!
