About 29 May 1942 the government and Douglas Aircraft Company, Inc., entered into a cost plus fixed fee ($1.00) contract (No. W-509-ENG-2557), whereby Douglas agreed to do all things necessary and incident to the procurement, furnishing, delivery and installation of equipment, machinery, machine tools, materials, supplies and facilities for proper operation of a Modification Center. Douglas established the Modification Center and operated it until the middle of 1944, when Army Air Forces deactivated the project. According to a narrative report contained in project files, there was no evidence of the lease ever having been executed, so it was believed that Douglas occupied and used the premises without any written agreement.
