I do wish that the Addison airport had enough space for them, what with the Cavanaugh Flight Museum already there. The B-29 was attached to that museum for a few years (the museum helped to pay for FiFi's new engines).
The old Braniff facility at Love would have been a good choice, but the White Citizens Council probably wouldn’t want those noisy propeller planes near the Bubble.
Then there is the old NAS Dallas - it’s underutilized at the moment (used to quarantine dogs exposed to Ebola, I think, and a few other minor uses - Texas air guard, some small reserve components, and maybe some of what little is left of Vaught). Should be plenty of room there, and the taxpayers have probably fixed the vandalism done by the navy when they left.
