U.S. Airmen from the Travis Air Force Base Honor Guard carry the casket of Col. Ernest De Soto, during his dignified arrival at San Francisco International Airport June 29, 2023. De Soto was killed in 1969 when his plane crashed into a mountain ridge during the Vietnam War. His remains were discovered in 1995, but it took more than 20 years for the Defense POW/MIA Accounting Agency (DPAA) to recover, identify and return them to his family in the Bay Area.
