AEDC team members look back on historical contributions during 70th anniversary of first wind tunnel

In the center of the transonic wind tunnel 1T at Arnold Air Force Base, Tennessee, shown here, is the 1-foot by 1-foot test section. Though no longer operational, the tunnel was used from 1952 to 1995. There, the transonic porous wall configuration was developed, which is a design still being used today in the 4-foot and 16-foot transonic wind tunnel at Arnold. (U.S. Air Force photo)
