KC-97A aerial tanker

Here a Boeing B-50 is refueled by a KC-97A aerial tanker, a variation of the Boeing Stratocruiser.  Both the B-50 and the Stratocruiser shared roots in the B-29 Superfortress, the B-50 was basically a re-engined B-29 with a larger tail. The Stratocruiser shared the B-29 wings, tail and lower fuselage.

Much the same scene 10 years later...
