We examine the orientation of winds in galaxy clusters indicated by the bending of jets into Wide-Angle Tailed radio sources. We find high confidence that the directions are not random, but are aligned with the surrounding supercluster, establishing a correlation between quantities two orders of magnitude apart in size. This is the first dynamical evidence in support of the "hierarchical pancaking" picture in which material collapsing to form structure falls into sheets and filaments before finally collapsing along the third axis to form collapsed bound objects (currently clusters).
