  High-energy cosmic ray events present important challenges to particle
astrophysics. Their nature and origin are often not well understood and, as
they occur in an energy domain not accessible to particle accelerators, there
is no clear guide to their interpretation. We recently proposed a new,
non-tachyonic, possible class of superluminal particles which may play an
important cosmological role. In this note, we would like to point out that such
particles, if they exist, are able to produce very high energy cosmic rays
compatible with discoveries reported in the literature.
