The coplanar emission of very high energy secondary cosmic rays was observed at stratospheric altitudes by the X-ray emulsion chamber experiments ECHOS-Concorde and RUNJOB. This paper treats the physical relevancy of the experimental observations using Monte Carlo calculations carried out with the help of the CORSIKA program. Different high energy hadronic interaction models have been used to study the possible dependence of this effect upon the primary particle mass number.
