After the failure of low-level flights and high-altitude balloons, the Americans now attempt aerial photoreconnaissance over the USSR with U-2 aircraft. A first U-2 takes off from the American military base in Wiesbaden, West Germany. It flies over Belarus, Ukraine, Poland, Moscow, Leningrad, and the Baltic States. The Soviets manage to track the plane with their radar (contrary to American expectations) but lack the weapons to shoot it down at an altitude of 23 kilometers.
