After reading case study from attached text book page 485, chapter-13, case study 13.3, answer the case study questions. 

1) Why are public works projects like the Honolulu Rail project nearly impossible to stop once they have been approved, even if later cost estimates skyrocket?

2) Project Management researchers have charged that many large infrastructure projects, like this one, suffer from “delusion” and “deception” on the parts of their advocates.  Explain how “delusion” might be a cause of ballooning budgets in this project.  How does “deception” affect the final project budget overruns?
