ED09-0157-02 NASA Dryden's F-18 #853 research aircraft that was the centerpiece of the Active Aeroelastic Wing project several years ago took to the skies again June 18 for the first time since 2007. The flight was a functional check following the extended downtime. The aircraft will replace Dryden's now-retired NF-15B #837 as the full-scale flight research test bed for NASA's Integrated Resilient Aircraft Controls (IRAC) program.
