F-16s fly over Arlington National Cemetery during a memorial service for 2nd Lt. Samuel G. Leftenant, United States Army Air Forces, Jan. 14, 2016, in Arlington, Va. Leftenant, a member of the Tuskegee Airmen, was reported ‘Missing-In-Action” on April 12, 1945, after the P-51 Mustang he was piloting collided with another P-51 while escorting bombers over Europe during World War II. He was declared dead in 1946, though no remains were recovered, and was posthumously awarded the Air Medal and Purple Heart. (U.S. Army photo by Rachel Larue/ Arlington National Cemetery /released)
