That story about the Russians and Americans on the moon sounds a little
far-fetched.  I would assume that they would have done the targeting well
enough to land the shells pretty close to the target.  But if they fired
a shell off at orbital velocity, any elevation in the firing angle would
cause the orbit to intersect the ground.  The shell would come back at
the same velocity vector at which it had left, so it would have to come
out of the ground.
