HAWKER SIDDELEY COMET 4

A BOAC Comet 4 was put into service Oct. 4, 1958, on the world's first transatlantic jet service. It was a longrange version of the basic Comet design and was easily recognized by the projection of the two-pod fuel tanks on the leading edge of each wing. Most of the flight tests for the Comet 4 were conducted on the one and only Comet 3 built by Hawker. A great deal of structural knowledge was gained through the unfortunate accidents of four of the original nine Comet I models. This knowledge was later tested on the model 3 and applied to the model 4. Following the model 4, the Comet 4B was produced for intermediate-range flights carrying a high-density passenger load. The model C-2 was a military cargo airplane and was structurally far superior to the original Comet 1.
