Ohakea Air Show 1958

Max has dug up some superb old black and whites that he took at an air show at Ohakea in 1958.
The Boeing B-47 Stratojet was powered by six general Electric jets and was classed as a long-range Medium Bomber.
Military Cargo and Troop Transport duties was the role of the Douglas C-124 Globemaster, with its four Pratt & Whitney radials, which each cranked out some 3800hp.
One of Britains famous three "V" Bombers, the Vickers BK-1 Valiant was a long-range Medium Bomber which could be converted to photo-reconnaissance or in-flight refuelling duties.
Thrust was supplied by four Rolls Royce Avons.
The other two "V" Bombers were the Handley Page Victor and the Avro Vulcan, both of which only performed bomber roles.
The massive tail fin could only belong to a Lockheed Hercules.
This would probably be a C-130A version with four 1750hp Allison turboprops driving 3 blade props. compared with  the current RNZAF C-130H models which use Allisons of 4910hp and 4 blade props.
Although the difference in top speed between the early and late is not considerable, the maximum take-off weight has improved by almost 25%.
Boeing's KC-97 Stratofreighter was a development of the civilan Stratocruiser.
The KC-97  could be used in either Transport or Tanker roles.
The big 4 blade props. were driven by Pratt & Whitney radials of 3250hp.
