We consider 5-dimensional real vector bundles over .
Isomorphism classes of these are given by their clutching function in
Given that is isomorphic to the surjection ,
we see that the vector bundle corresponding to times the generator
has a sphere bundle which is fiber homotopically trivial, so in particular we have
homotopy equivalences
