That's a ridiculously high probability. Human bodies don't cover 1/1000 of
the earth. Maybe they mean 1:1000 of hitting a structure?

Seems like a clean solution to the problem would be to put a "killer
in orbit. The killer could change orbits and would carry a capture device
like some properly chosen cloth. The killer captures the out-of-control
target and drops both to controlled re-entry. One "killer" could insure many
such potential problems.
