Great photo of U-2 pilots getting ready for the commemoration of the 1st Reconnaissance Squadron’s Centennial.

 
From WikiPedia: The 1st Reconnaissance Squadron is a United States Air Force reconnaissance training unit based at Beale Air Force Base, near Marysville, California. It is the oldest squadron in the Air Force, and the first organization to be established as a U.S. military flying unit. Since 1922 the 1st Squadron has been associated with the USAAF 9th Bomb Group and the USAF 9th Reconnaissance Wing, where it continues to be an active flying training unit operating the Lockheed U-2 and the RQ-4 Global Hawk surveillance aircraft.
