After Bruce escapes The Pit in The Dark Knight Rises he travels to Gotham City, however The Pit is located in South Africa and Gotham City is located half-way across the world in North America. At this point in the story Bruce is completely broke, and he has no access to any of his remaining resources anyways, so I don't see how he could acquire transportation to Gotham City. He also seems to do this in the span of a few hours, even though it should take roughly 17 hours to travel from South Africa to North America.
How does Bruce manage to travel from The Pit to Gotham City?
