Not sure if this has been discussed, but saw the sign while cruising around the airport today.
CVG | Mesaba Hangar
The site is located on the south side of the airport just east of the center runway (18C/36C). The hangar measures approximately 282 feet wide by 190 feet deep (62,670 sq. ft.) The hangar door measures 43 feet high by 258 feet wide. Utilities and airfield access are readily available. The building also offers 62,860 sq. ft. of offices, shop space, storage space, classrooms and a kitchen.
In case anyone wants to open, you know, a bar or something.
