Hi!
What's wrong with the following method of seeing what life is like inside a black hole and escaping? I can't see anything obvious. We'll assume that time scales and tidal forces aren't an issue (it's obviously impractical -- but is it impossible)?
1. Get a spaceship which can travel at c (well, as close to c as you can imagine).
2. Fall into the black hole. Just below the event horizon, inside the hole, fire your rocket engine as fast as you can. This will slow your descent to an arbitrarily slow speed, though not stop it (and certainly not escape). In effect, you will be able to "hover" there as long as you want.
3. The black hole emits Hawking radiation and starts to lose mass. This causes the event horizon to retreat inward.
4. The retrating event horizon passes over your hovering ship. Your ship is now outside the event horizon.
5. You escape.
