Blackbird Airpark, an annex of the Air Force Flight Test Center Museum at Edwards Air Force Base, offers a look at the unique Blackbird series of military aircraft. Included in the collection are the Lockheed SR71A Blackbird reconnaissance plane, its predecessor, the A12 test plane, and the ultrasecret D21 drone. The recently completed Blackbird Heritage Wall commemorates the designers, crew members and others associated with the aircraft. The museum and its gift shop are open Friday through Sunday, 10:00 am. 5:00 p.m.
