On June 10, 1970, Maj. Robert Perry, DIA’s assistant army attache to Jordan, was shot and killed by Palestinians in Amman. Perry was DIA’s first duty-related death. Five years later on April 4, 1975, while the 87 DIA employees deployed to Saigon were leaving Vietnam, five officers perished, in a plane crash as part of Operation Baby Lift. This would be the highest loss of DIA lives in a single event until the Sept. 11, 2001 attack on the Pentagon.
