The terminals at DFW have remained the same in FS over the past 6 to 8 years... but much in real life has changed, the DFW in FSX and FS9 is dramatically different from the real life DFW international.
anyone interested in designing the new "terminal D" and erecting the "skylink" train system with an animated 2 car electric train? many photos are available on the web.
edit: Also perhaps a couple of static 767s or MD80s in various states of repair and maintenance on the AA, fedex, UPS and Delta Ramps (engines exposed or cowlings opened etc)
