To Go or Not to GoWritten by Michael Leighton
No doubt you have read a multitude of editorial on the subject of the Go/No Go decision. In reality, it should probably be called the Go On/Not Go On decision, since Go/No Go implies that the decision is made on the ground prior to departure. But in the real world, that is not always the case.
In fact, accident investigators talk about the decision chain, the series of events followed by a pilot's decisions based on those events that eventually lead to an incident or accident. Many of these decisions are made after departure and before arrival, planned or unplanned.
