ARLINGTON, Va. — In the days after she became sick with the cancer that eventually took her life, Jacquelyn McGouldrick gave her friend Liz Flick two bottles of champagne and an order: Keep these for when her husband came home. Air Force Col. Francis Jay McGouldrick Jr. had gone missing on Dec. 13, 1968, after a midair collision with another U.S. aircraft over Laos. Jacquelyn McGouldrick and her four daughters were left in a limbo as days, then decades, passed. Yesterday, they finally opened the bottles.McGouldrick was home.
