✦ Synopsis
We present an efficient hybrid method to simulate the longitudinal development of ultra-high energy air showers, accounting in detail for muon production and fluctuations. Applying this hybrid method to the simulation of extensive air showers with QGSJET and SIBYLL, the predictions of the two hadronic interaction models are discussed in light of their importance for the longitudinal shower profile and muon production.

Air shower simulations have been studied for dependence on features of the initial proton-air collisions at 101°eV. Comparisons are made between results with Sibyll and QGSjet hadronic interaction event generators. ## 1. I n t r o d u c t i o n Detailed simulations and understanding of giant air s
To investigate the impact of uncertainties in the knowledge of properties of individual hadronic interactions on the development of extensive air showers, the inelastic proton-proton cross section and the elasticity of interactions have been modified within the interaction model QGSJET.

An idea that exact Lorentz invariance can be violated was proposed by Coleman and Glashow to overcome the astrophysical problems with giant air showers. In view of this idea neutral pions do not decay at high energies, resulting in a faster shower development. As a consequence, the depth, X,,,, of
