We discuss the possibility that diffraction scattering of hadrons conserves the s-channel helicities of the particles involved. Presently available experimental data is examined and shown to support conservation of s-channel helicity, and not the hypothesis of no helicity,flip in the t-channel. Further tests are suggested and restrictions imposed on various models of diffraction scattering, in particular, t-channel exchange models, are discussed. (Submitted to Phys. Letters B) t Work supported by the U. S. Atomic Energy Commission.-2-Diffractive processes are an important if not key part of high energy hadron-hadron collisions. Yet in many ways such processes are the least understood. Diffraction phenomena seem to lie outside the picture which connects s-channel resonances and some t-channel exchanges’. Within the Regg
