  We report interferometric mapping of the bipolar pre-planetary nebula IRAS
08005-2356 with an angular-resolution of ~1"-5", using the Submillimeter Array
(SMA), in the 12CO J=2-1, 3-2, 13CO J=2-1 and SiO J=5-4 (v=0) lines.
Single-dish observations, using the SMT 10-m, were made in these lines as well
as in the CO J=4-3 and SiO J-6-5 (v=0) lines. The lines profiles are very
broad, showing the presence of a massive (>0.1 Msun), extreme high-velocity
outflow (V~200 km/s) directed along the nebular symmetry axis derived from the
HST imaging of this object. The outflow's scalar momentum far exceeds that
available from radiation pressure of the central post-AGB star, and it may be
launched from an accretion disk around a main-sequence companion. We provide
indirect evidence for such a disk from its previously published, broad H-alpha
emission profile, which we propose results from Ly-beta emission generated in
the disk followed by Raman-scattering in the innermost regions of a fast,
neutral wind.
