NASA Langley's Hypersonic Facilities Complex, 1969. A hypersonic wind tunnel is designed to generate a hypersonic flow field in the working section, thus simulating the typical flow features of this flow regime - including compression shocks and pronounced boundary layer effects, entropy layer and viscous interaction zones and most importantly high total temperatures of the flow.
In 1967, Congress granted approval for the construction of Tunnel 9. The facility became operational in 1976 and has since been providing aerodynamic simulation in critical altitude regimes associated with strategic offensive missile systems, advanced defensive interceptor systems, and hypersonic vehicle technologies.

U.S. aerospace company Stratolaunch conducted the first powered test flight of a new unmanned craft for hypersonic research on Saturday and called it a success. Chief Executive Officer Zachary ...
The T4 shock tunnel began operation in April 1987 and commenced routine operation, after a commissioning period, in September 1987. The 10000th shot of T4 was fired in August 2008. The University of Queensland also maintains the X2, X3, and X3R facilities. X3R now outclasses the T4 facility. [10]
The U.S. Navy test-launched a powerful SM-6 supersonic missile from a container mounted on its smallest type of surface warship: the Littoral Combat Ship (LCS).
Three former workers in a Northern California office of the Zurich American Insurance Co. who were fired after taking “off-the-record” paid time off were awarded more than $80 million in ...
