"Two soldiers comfort each other under the strain of combat in Pleiku, South Vietnam, 26 May 1967. Pleiku was strategically important during the Vietnam War because it was the primary terminus of the military supply logistics corridor extending westwards along Highway 19 from the coastal population centre and port facilities of Qui Nhơn. Additionally, its central location on the plateau, between Kon Tum in the north, Buôn Ma Thuột to the south, and the North Vietnamese Army's base areas inside Cambodia to the west made Pleiku the main center of defense of the entire highland region of the Republic of Vietnam. This was obvious to both sides; the United States established an armed presence very early in the conflict at Camp Holloway, and the Việt Cộng attack on this base in early 1965 was one of the key escalating events that brought U.S. troops into the conflict. On 15 June 1972, Cathay Pacific Flight 700Z, operating a Convair 880 from Bangkok to Hong Kong, disintegrated and crashed while the aircraft was flying at 8,800 m. over Pleiku, Vietnam after a bomb exploded in a suitcase placed under a seat in the cabin, killing all 81 people on board."
