I don't think it's possible to orbit inside the Sch. radius, R_s.
Interestingly, you can't even orbit between r = R_s and (3/2)R_s
unless you are firing your rockets.

Subject: [Phys-l] Blackhole Orbit
When discussing the misconception that black holes 'suck everything
in' , a neat question came up: Would it be possible to orbit a black
hole inside the Schwarzschild radius? Would you still be weightless?
My _guess_ is that that answer is yes you can orbit, but tidal
differences would produce strain.
(smart mouth answer: no one will ever know.)
Cannot find anything on the web. Some cryptic references to orbits
not being stable closer than a certain radius.
Opinions? I did tell the student that I would ask the more enlightened.
