We report the discovery of bent double jets in the elliptical galaxy NGC
1272, a member of the Perseus cluster. The jets have a radius of curvature of
~2 kpc, much smaller than the galaxy half-light radius of ~11 kpc. This bending
is likely a result of ram pressure, and indicates that the intracluster gas
enters deep within the galaxy and that the interstellar medium of NGC 1272 has
been significantly removed. X-ray observations of the surrounding intracluster
medium allow us to constrain the pressure within the jet. We find that the
standard assumptions of equipartition often used in interpreting other jets
underestimate the pressure in the jets by a factor ~30.
