That is when the huge explosion happened. 37 seconds after the launch, Cluster spacecraft provided us with one of the most expensive fireworks in the history of humankind. Totalling $370 million in cost.
As Kevlin Henney has demonstrated time and again, majority of our critical failures are actually a result of incorrect handling of the trivial errors in older parts of our code or system. And that is exactly what we can find at the root of the Cluster incident as well.
Its really curious, because the biggest errors actually might not be the errors of the system at their core.
It is far more likely that they are errors of our habits.
