          In this note we consider submersions from compact manifolds, homotopy equivalent  to the Eschenburg or Bazaikin spaces of positive curvature. We show that if the  submersion is nontrivial, the dimension of the base is greater than the dimension of  the fiber. Together with previous results, this proves the Petersen-Wilhelm conjecture  for all the known compact manifolds with positive curvature.
