Prepar3D v5 Scenery--Ontario International Airport KONT, California (CA), USA. This scenery will update the default Ontario International Airport (KONT) in P3D v5. Designed as accurately as possible with great frame rates. Example photos were taken using REX Worldwide scenery update and GSX (both not required), so building textures may differ if you are not using REX. Update scenery is a completely a stand-alone. Nothing else is needed. By Wendell Melton.
