Small Supersonic Tunnels
The small space available for the SSTs between the AWT and the IRT is clearly evident in this April 1955 view, which also shows the inlet duct from the make-up air dryer at lower right. Note the gate valve in the top tunnel’s inlet duct, the top of the exhaust manifold at top center, and the make-up air duct to the AWT at the left.
