That fact that they managed to dug a 600 ft tunnel, two football fields, is pretty darn amazing and points out some serious flaws in oversight of the prison.

Or they found the tunnel earlier, waited until it was almost finished (thanks, seismic sensors!) and the escape attempt was about to be made, then collected all the responsible parties.
