Decommissioned Mach 8 tunnel removed to make room for future test opportunities
Marshall Brown, a former AEDC engineer, checks a model suspended in the Tunnel E wind tunnel at Arnold Air Force Base in January 1972. In Tunnel E, a magnetic model support system (MMSS) was used, which eliminated the need for strut or sting supports that generated unwanted disturbance in the wakes of the model. Models weighing up to 20 pounds could be tested with the MMSS. (U.S. Air Force photo)
