Operator boredom. Launch fatigue. Falling asleep at the wheel. Even the most experienced launch technicians can suffer from it. During a routine launch, something distracts the operator. Before anyone realizes, it a multi-million dollar rocket and payload is heading for the ground instead of the stars.
To avoid rocket loss due to launch fatigue, Centauri Spaceworks has contracted with Nooleus to provide 1000 quick launches. This will supply Centauri with the fuel and modules it needs to continue building ships and stations without the time, effort, and risk of doing every launch. Centauri will still continue to do crew and consumable supply launches as needed.
