In the report, all the data pertinent to an experimental investigation of the effect of loading system rigidity on the initial buckling load of unreinforced circular cylindrical shells under hydrostatic pressure are presented. According to the commonly accepted Tsien criterion the buckling pressure should be higher in a rigid system than in a soft system. The research denies this axiom by generating strong evidence that the stiffness characteristic of the loading system does not alter the initial buckling stress, which fully supports the results obtained by Kaplan and Fung on spherical caps, by Krenzke on plastic spheres, and by Carlson, Sendelbeck, and Hoff on nickel- plated spherical shells.
