The energy-momentum tensor of a supersonic heavy quark jet moving through a strongly coupled SYM plasma is analyzed in terms of first-order Navier-Stokes hydrodynamics. We focus on the near zone 'head' region close to the heavy quark where deviations from hydrodynamic behavior are expected to be large. For realistic quark velocities, v = 0.99, we find that the non-hydrodynamical head region is confined at a narrow pancake surrounding the jet with a width ∼1/T and transverse radius ∼3/T. Outside this jet head region, the jet induced stress is well approximated by Navier-Stokes hydrodynamics.
