  We develop a model of SGR in which a supernova leaves planets orbiting a
neutron star in intersecting eccentric orbits. These planets will collide in
$\sim 10^4$ years if their orbits are coplanar. Some fragments of debris lose
their angular momentum in the collision and fall onto the neutron star,
producing a SGR. The initial accretion of matter left by the collision with
essentially no angular momentum may produce a superburst like that of March 5,
1979, while debris fragments which later lose their angular momentum produce an
irregular pattern of smaller bursts.
