Start with recently mothballed large airbases. Add industrial airports. Add active airbases that have excess land. Cecil Field, Fla. Carswell and the San Antonio fields in Texas. Alliance Airport in Texas. Old NAS Dallas. I don't know if the Winder, GA airport runway is long enough (5500 feet) but Joint Reserve Base Dobbins could handle the planes. And there is a lot of empty space at Plant 6 there. Kansas City airport is underutilized.
The old ABX/DHL Airpark in Wilmington, OH. Former national freight hub, two nice sized runways. And room to grow (East and South). Several hundred thousand SqFt of warehouse space could be converted to sub-assembly bays. Truck docks out the wazoo. Even has its own ATC tower.
And, genuinely nice folks in the region.
About equally close to Cincinnati, Columbus, and Cleveland.
Carswell is far from mothballed. It is actually very busy.
