We present data from ..pi../sup -/p ..-->.. elastic and rho/sup -/p final states for scattering at 90/sup 0/ center of mass, -t = 9 GeV/sup 2//c/sup 2/. A large rho/sup -/p signal is seen and the rho/sup -/ is strongly polarized. This polarization tests a QCD prediction that quarks cannot flip helicity. The test fails dramatically. 9 references, 4 figures.
