Hello all! OMA Concourse A is is finally complete(or sorta - I guess I'm never really done with the detail). I did end up touching up all the gates to provide more detail including about four perpendicular slider gates on 1,8,9 & 10. The slider gates look very old, maybe about from the 1980's or 90's (someone can let me know if you have any other information on that). I also completed some electric boxes and roofing detail on vents, outlets, etc. There are also the four leased gates by Delta Airlines which have the Delta logo signage that I added on gates 2,3,4 & 5.
The images include the last available satellite shots via Google Earth of Concourse A before the construction began joining concourses A and B to one main terminal. There's also a gate number map from the old Concourse A to see the numbers I listed above.
I'll still be working on some GSE to match the airport as well as a few touch-ups. Enjoy and thank you all again for the replies!
