Great documentary about Air Refueling that aired on the Military Channel.
This is the refueling scene from the movie “Strategic Air Command”. In this scene a B-47 is refueled from a KC-97L. The KC-97L is easily identified by the addition of two J-47 turbojet engines under the wings outboard of the R-4360 radials. The J-47s gave the KC-97 a higher top speed which allowed it to refuel the new breed of high speed jet powered aircraft. The KC-97L was a stopgap measure until the KC-135A Stratotanker came online.
