We consider taking the opportunity of about 10.000 hours of test of the Airbus A380, and to install at passenger space detectors for high energy cosmic ray events. The altitude of 10 km (250 g/cm 2 ) would give opportunity to measure EAS originating from heavy primaries to energies exceeding 10 7 GeV, and also coming without interaction proton component beyond the energy of the knee. At the altitude the iron originated EAS are well developed and registering their lateral distribution in 70 meters long cabin it is possible to distinguish them from proton originated EAS. Hadron component of EAS (registered as number of secondary hadrons produced in the detector) would help in discrimination and energy estimation. On another hand, registrations of high energy protons (without EAS) would enable to measure high energy proton spectrum. The energy of the proton would be estimated via hadron multiplicity in single interaction inside the detector. We propose to use about 60 modules of 0.5 m 2 of active detectors with scintillators to detect E-M component and carbon target with lead layer to detect the hadronic component via neutron registrations.
