FSX/P3D. So indeed as part of their Worldwide Airport HD project, REX will indeed be adding more FREE Enhanced Add-On Airport Packs to existing customers to further enhance your favourite destinations. This is also a very welcome sight in an age where many new developers are arriving on the scene peddling junk on Simmarket for $17 bucks or more. Thanks to Orbx for giving even better quality away for free in their own freeware global addon packs! 

What's even better is the the REX enhanced airports quality surpasses Blueprint's paywares by a HUGE margin. Indeed these enhanced airport addon packs will be a terrific addition to Worldwide Airports HD! SLC shot shown above but i'll post the first DCA shots soon as they arrive! Thanks to ADX systems builder Greg Sanderson for the tipoff!
