The U.S. Air Force's F-16D Automatic Collision Avoidance Technology (ACAT) aircraft eclipsed the sun during a flight in March 2009. NASA's Dryden Flight Research Center worked with the Air Force Research Laboratory in the ACAT Fighter Risk Reduction Project to develop collision avoidance technologies for fighter/attack aircraft that would reduce the risk of ground and mid-air collisions.
