For StarTrek fans, the University of Queensland Laser Diagnostics Dept. tested the USS Enterprise in their super-orbital expansion tube - X2. A scale model was placed in the test section and the facility used to generate a high speed gas flow of around 6.6 km/s. This was passed over the Enterprise for a duration of approximately 100 microseconds. They performed similar tests on other models investigating dissociation and ionisation processes which occur during atmospheric re-entry.
