Experimental results from Haverah Park, Yakutsk, AGASA and Fly’s Eye are reviewed. All these experiments work in the energy range above 10 eV. The ’dip’ structure around 10 eV in the energy spectrum is well established by all the experiments, though the exact position differs slightly. Fly’s Eye and Yakutsk results on the chemical composition indicate that the cosmic rays are getting lighter ov...
