There're thousands of add-ons on the Web for the classic FSX and Prepar3D v1 to v3. Take off from anywhere in the world, flying some of the world’s most iconic aircraft to any one of 24,000 destinations.
With the Handley Page RAF Victor download (which flies really well by the way) there is a video of a take-off from Tengah and landing at Changi, both on Singapore.
But where does the superb scenery come from please? Does anyone know?
