306 High in Air B-50 Drinks Its Fill. In This New Age, Bombers Can Circle World Nonstop Refueling at about 200 miles an hour over Puget Sound, a B-50 Superfortress gulps gasoline from a B-29 tanker plane through Boeing's new flying boom, developed for the Air Force. Last year the B-50 Lucky Lady II made history's first nonstop round-the-world flight, covering 23,452 miles in 94 hours and one minute with four refuelings by an earlier hose-type device. This new telescoping boom greatly speeds the process. The V-shaped "ruddevator," like the control surfaces of a plane, enables the operator to fly the boom into the open slipway doors. Heated rubber strips on the V's leading edges prevent icing. Experimentally, even jets now are refueled in flight.
