can anything at all fall into a black hole?

hi folks

I wonder if anything can fall into a black hole rather than just stay at
the event horizon.

According to general relativity the curvation of space-time, when approching
the event horizon,gets infinite. The spacetime near a black hole should
look like this: (only 1 dimension of space is drawn)

   event horizon= 3d-edge of the black hole

singualrity=black hole

the line (from A to B) drawn above is actually the 3d hyperspace (were we
live in) inside the 4 dimensional spacetime. so we can only travel along
this line!

suppose a spaceship at point (A). the captain, a curious but apparantly not
an intelligent one, wants to fly into the blackhole. after the spaceship
starts at point (A) it follows the line drawn above and appraches the black
hole. but it can never actually go into the black hole, because it cannot
leave this curved line.
so the spaceship (totally squeezed) ends up at the 3 dimensonal
event-horizon (B).
(time and space there would be rectangular to spacetime at point (A).)

so why should anything cross the event-horizon and go to the center of a
black hole? what's wrong about my argumentation, or isn't it wrong?
