I just wanted to throw my hat in on this one. I was stationed at Spangdahlem from 2006-2014, and a member of the 81st. The A-10's should fit snugly into the HAS's there(a few feet of clearance from either wingtip). We did not modify them at all(they were the larger gen III's). We used the shelters on the western portion of the airfield.
Also, I'm curious about the elevation data for Spang. It was an airfield that was not flat at all, lol, we had to climb uphill from our parking spots on the way to the 23 EOR. I figure there will be adjustments as the map progress develops.
So far, I am really digging it though!
