At the other plane. A KC-135 Stratotanker hangs in the frame, boom extended, feeding fuel into the most capable strike aircraft the United States has ever built. That tanker entered service in 1957. Eisenhower was president. The Soviets had just put Sputnik in orbit. The aircraft keeping America’s sixth-generation stealth bomber airborne was already flying when tailfins were still standard equipment on family sedans — and nobody in the Pentagon’s press release felt the need to mention that.
