Query: Proton-Proton Total Cross-Sections from the Window of Cosmic Ray
  Experiments   The importance of cosmic-ray experimental measurements of proton-proton total
cross sections to understand the underlying fundamental dynamics is discussed.
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.
