Abstract: Let $ (\sigma ,\,Z)$ be a metric minimal flow. Let Y be a compact metric space and let $ \mathcal{g}$ be a pathwise connected group of homeomorphisms of Y. We consider a family of skew product flows on $ Z\, \times \,Y\, = \,X$ and show that when $ (\mathcal{g},\,Y)$ is minimal most members of this family have the property of being disjoint from every minimal flow which is disjoint from $ (\sigma ,\,Z)$. From this and some further results about skew product flows we deduce the existence of a minimal metric flow which is disjoint from every weakly mixing minimal flow but is not PI.
