Air crash investigators probing Flight MH370 will need to counter the public demand for a quick answer as they begin the long-term safety analysis.
What happened to the Malaysia Airlines Boeing 777 will likely remain a mystery for some time, even if or when any wreckage from the southern Indian Ocean is finally identified.
At the moment, we still don't know what happened to the plane carrying 239 passengers and crew from Kuala Lumpur to Beijing.
All we have is Malaysian Prime Minister Najib Razak's announcement that the plane is now believed to have crashed with no survivors.
But the urge to make sense of it all and to find a scapegoat is a human tendency. It's also natural for the travelling public and those who are awaiting news of their loved ones on board the plane to seek answers.
The goal of any safety investigation is to understand what happened, identify any lessons learnt and implement any safety actions needed to prevent a tragedy like this happening again.
The systems safety perspective teaches us these three important lessons for this investigation that counter that initial urge to find answers quickly.
The main principle of a systems safety perspective is that several contributing factors may be found. They could be in the technology and crew operating close to the accident. They could also be in different organisational elements whose decisions and actions are further removed from the accident, both in time and place.
Part of what went wrong with Flight MH370 may be a symptom of underlying issues in the wider system. If these elements remain unaddressed and only people and technology operating close to the accident are looked at, the safety issue may occur again for another crew or plane.
The major rail accident in Santiago de Compostela, Spain, on July 24 last year was shaped by factors across the rail transport system, most of which were beyond the control of the driver.
But initial reports focused heavily on the driver, who was speeding. The driver was readily blamed and blamed himself for this accident.
From a systems safety perspective, this accident was waiting to happen. For example, that particular bend in the rail track was known to be dangerous but nothing had been done about it.
The route the train was travelling on was equipped with an automatic speed control system (European Rail Traffic Management System), but this system was not in place at the part of the track where the accident happened.
If these systems safety factors across the rail system remain unaddressed, the accident may happen again to other drivers.
The systems safety perspective also reminds us that accidents may not have been caused by one single failure. Rather, it may have been an unlucky concurrence of events and behaviour that have happened many times before in isolation.
