The Convair CV-340 was a direct successor to the CV-240 and a derivative of the earlier
type. The Convair CV-340 is essentially a stretched CV-240. It differs from the 240 in having a 54-in. longer fuselage permitting an
increase in passenger capacity to 44, and increased wing span and area. The N3401 of Consolidated-Vultee Aircraft Corp., the prototype of the CV-340 flew
first on 5 October 1951. The first delivery of the CV-340 was the N73103 to United Airlines on 28 March 1952.
The CV-440, a refinement of the CV-340, flew first on 6 October 1955. This model has increased dimensions, giving a higher pay-load and
take-off weight, and improved range. The aircraft is known as the
'Metropolitan'. A total of 209 Convair CV-340s were built, followed by 186 Convair CV-440s.
The Norwegian air charter company Nor-Fly A/S operated a number of Convair CV-440's. Nor-Fly A/S used Eelde
airfield in the Netherlands for refuelling on trips from and to Norway. On 2 October 1977, Convair CV-440 LN-KLK was
photographed at the Eelde tarmac when waiting for passengers on a charter from and to Oslo.
