The interior of this hangar is a work of art. Reminds me of the complex mathematically inspired lithographs by Dutch graphic artist M.C. Escher (June 17 1898 – March 27 1972).
This is at the Barstow-Daggett Airport originally built in 1933. During World War II it became home for A-20 Havoc bombers and P-38 Lightnings. Eventually taken over by the Fourth Air Force tasked as air defense for the Western United States. Now maintained by the County of San Bernardino.
From a recent photo excursion and photographed on a Fujifilm X-H1 camera with the Fujifilm XF16-55mm f2.8 lens.
