The situation might be as follows. A successful end result is incredibly important. The emphasis on achieving a result could not be greater. The process of getting there is tense. It is littered with potentially disastrous problems. There can be no admission of this. Failure is not permitted. As the process continues the sense of urgency grows.

But what if there is no breakthrough - what is Plan B? Plan B? There is no Plan B.
