These are some remarkable pics. Hangar One is identical to the TCOM hangar at the former Weeksville Naval Air Station outside of Elizabeth City, NC. The TCOM hangar is the current home of the M1400 airship. The third such hangar is located at the Lockheed-Martin facility in Akron, OH. To the best of my knowledge, these are the only three such hangars of this vintage ever constructed.
Judging from these pics, TCOM will have its hands full if it ever decides to re-skin the hangar
