 Detachment "A", with four U-2 aircraft, arrived at Giebelstadt from Wiesbaden Air Base in October 1956, the reason being that U-2 operations from the relatively isolated Giebelstadt would draw much less attention than from Wiesbaden.Towards the end of the year, Detachment A flew U-2s three times over Albania, Bulgaria, Romania and Yugoslavia.The Detachment was operational at Giebelstadt until 15 November 1957, when it was closed down, and U-2 operations were moved to Pakistan.
