That makes it a bit more complicated. I was referring to the exact radius at which light can not escape from a non spinning black hole as observed from far away. If a space ship reaches that radius from our perspective, it would totally blink out of existence.
No. Actually, nothing happens to the spaceship. Neglecting tidal forces or other effects from the environment near a black hole, it doesn't even experience the event horizon as anything special. Ummm.... it might start to see things that can't be seen from outside. Like what is in the hole and what is on the other side.
What happens is that the space ship becomes unobservable to us, except the mass is still there. The mass of the black hole increases by it. If I'm correct, gravity is the only observable that remains.
