We combine infrared, optical, and X-ray observations of the supernova remnant Cassiopeia A to produce a new kinematical model of the explosion. The three-dimensional model is based on a Doppler reconstruction of both shocked and unshocked ejecta as well as the distribution and segregation of gaseous and dusty material from different nucleosynthetic layers. We find that the reverse shock is spherical, but the ejecta distribution is flattened and oriented approximately 20-30 degrees from the plane of the sky. The well-known northeast and southwest jets are also found in this plane. The distribution of the Fe-rich emission suggests that the ejecta were expelled in a series of "blowouts" in the flattened ejecta plane. We predict that the unshocked ejecta, currently interior to the reverse shock, will cause a dramatic brightening of Cas A over the next century.
