According to the NASA release, on the same day, the space agency tested the experimental Morpheus lander, Starfighters Aerospace tested "modified jet fighters through their afterburner evaluations, and medical evacuation helicopters conducting safety checks and procedure tests."
This flurry of activity was taking place at the same time the facility was under construction.
The uniqueness of the March 11 test day was that the runway was used by a multitude of people for a variety of reasons. Prior to March 11, the facility made famous by rocket launches and space shuttle landings was used by only one group at a time.
While this particular test was the first to mention a NASCAR team, the Kennedy Space Center's Shuttle Landing Facility has hosted "car tests" in the past. It is unclear whether any of these previous tests were conducted by NASCAR teams or not, and attempts to contact NASA were not returned at time of publication. (FOXSports)
