You might enjoy the article that I just referenced above.
I like your thought experiment. You’ll have to work out some way for the spaceship not to be torn apart by tidal forces. Maybe if the black hole were particularly huge, or if the craft were particularly devious in its design.
Exactly. It is well known that a solar system-sized Black Hole (with a mass a billion times that of our own Sun) could be easily entered into by a human space traveler, without being torn apart - very moderate tidal forces.
Or a small, automated space probe - only 10 cm in diameter...
