Description:
    The simple unification scheme of powerful radio galaxies and quasars,
    based entirely on the orientation dependent effects, has been
    confronted with the observed radio structures for 152 radio galaxies
    and 173 steep spectrum quasars. Contrary to the scheme's prediction,
    the cosmological evolution of geometrical parameters describing the
    large scale structure of these two types of radio sources are
    different.
