A review of recent NASA Langley Research Center experimental aerothermodynamic contributions to slender and winged hypersonic flight programs is presented. Significant findings and lessons learned are highlighted and discussed for a range of high profile national flight programs. In many cases, the experimental results are shown to be crucial to the success of these programs. To assure success with future hypersonic flight programs, experimental aerothermodynamic facilities will be required to provide invaluable support both pre- and post-flight.
