It is shown that early discovered global structure of proton-proton total cross section [5,17] is completely compatible with the values obtained from cosmic-ray experiments.The talk presented at the IXth Blois Workshop, Pruhonice near Prague, June 9-15, 2001, Latex2e, 7 figures, this version was sent for publication in the Physics Letters B; misprints in caption for figures removed, improved cosmic ray data from current database includedHigh Energy Physics - PhenomenologyAstrophysicsProton-Proton Total Cross-Sections from the Window of Cosmic Ray Experimentstext
