 Throughout its period at Ubon , No. 79 Squadron formed part of an international force tasked with defending Thailand 's air space against intruders . At the start of the deployment , tensions in Thailand were such that the squadron 's personnel believed that they were at war . While the situation became more stable from late July 1962 , No. 79 Squadron maintained armed aircraft on alert at all times and scrambled Sabres when unidentified aircraft were detected . No air attacks were conducted against Thailand , however , and the unidentified aircraft that were intercepted almost always proved to be from the Central Intelligence Agency @-@ controlled Air America . In January 1965 two Sabres accidentally overflew North Vietnam after becoming lost during a training sortie but returned safely to Ubon .
