Well, I didn't see that these were specifically "F-4E" skins, my apologies. I thought that leaving the GPS coordinates of Getafe's roundabout would have been useful for Heatblur (you never know)
Being strict with the conditions: "F-4E" version and available maps; probably we are limited to Israel, Turkey, Iran and a few from USAF. Honestly, all the skins probably represent 5% of a sim project. Heaviest part is the cockpit modeling (20%), but above all the programming and test (75%). And unfortunately what a programer does, can rarely be done by a modelling artist (and vice versa). But yes they will have more work on the skins than what they had with the Viggen and the F-14.
