Vintage warbirds take to the sky during a formation flypast at a Tennessee air museum airshow, June 2014. The lead aircraft's profile is consistent with a Douglas A-1 Skyraider, the rugged attack aircraft flown extensively during the Vietnam War by U.S. Air Force, Navy, and Air Commando pilots. Airshows like this one preserve the memory of these aircraft and the veterans who flew them. Project: 219310
