Correlations between the position angles of galaxies and the major axes of their parent clusters or superclusters are searched for in two large galaxy catalogs, the UGC and the EUC, which cover most of the sky to a diameter limit of 1'. A variety of subsamples are tested, focusing on the prominent structures such as the Local Supercluster and the Perseus-Pisces Supercluster, together or separately, at different levels of density contrast, at various depths, and for different galaxy types. The results are consistent with no correlation. This null result challenges the cosmological dissipative pancake scenarios, e.g., based on massive neutrinos or on explosive shells, where galaxies are assumed to have formed by fragmentation in pancakes.
