CIA overflights of Asian targets began in spring 1958 when Detachment C moved from Japan to Naval Air Station Cubi Point in the Philippines to overfly Indonesia during an uprising against Sukarno's "Guided Democracy" government. The CIA's Civil Air Transport, aiding the rebels, so badly needed pilots that it borrowed two CIA U-2 pilots despite the high risk to the U-2 program if one were captured. The Indonesian government soon defeated the rebels, however, and the U-2s returned to Japan. That year, Detachment C also flew over the Chinese coast near Quemoy during the Second Taiwan Strait Crisis to see if Communist Chinese forces were preparing to invade, and in 1959 aided CIA operations during the Tibetan uprising. The unit was collecting high-altitude air samples to look for evidence of Soviet nuclear tests when it was withdrawn from Asia after the May 1960 U-2 incident.
