  We present high sensitivity maps of the High Velocity (HV) CO emission toward
the molecular outflows around IRc2 and Orion-S in the Orion A molecular cloud.
The maps reveal the presence of HV bullets in both outflows with velocities
between 40-80kms-1 from the ambient gas velocity. The blue and redshifted CO HV
bullets associated with the IRc2 outflow are distributed in thin (12"-20",
0.02-0.04pc) elliptical ring-like structures with a size of ~10"x50"
(0.02x0.1pc). The CO emission at the most extreme blue and redshifted
velocities (EHV) peaks 20" north of source I, just inside the rings of the HV
bullets.
  The low velocity H2O masers and the H2* bullets around IRc2 are located at
the inner edges of the ring of CO HV bullets and surrounding the EHV CO
emission. Furthermore, the high velocity H2O masers are very well correlated
with the EHV CO emission. This morphology is consistent with a model of a jet
driven molecular outflow oriented close to the line of sight.
  In the Orion-S outflow, the morphology of the CO HV bullets shows a bipolar
structure in the southeast-northwest direction, and the H2O masers are found
only at low velocities in the region between the exciting source and the CO HV
bullets.
  The morphology of the CO HV bullets, the radial velocities and the spatial
distribution of the H2O masers in both outflows, as well as the H2* features
around IRc2, are consistent with a model in which these outflows are driven by
a jet variable in direction.In this scenario, the large traverse velocity
measured for the H2O masers in the IRc2 outflow, ~18kms-1, supports the
evolutionary connection between the jet and the shell-like outflows.
