The suggestion by Bryant et al. (1992) that 'high flyers', which result from a statistical excess of head-on versus overtaking collisions in Fermi acceleration, can account for acceleration of cosmic rays to about 10 exp 20 eV is discussed critically. It is shown that the statistical approach of Bryant et al., with some corrections, is equivalent to diffusive Fermi acceleration. The 'high flyers' result from diffusion in energy, which complements systematic acceleration by redistributing the particles in energy space, and does not lead to more effective acceleration to higher energies as claimed.
