I'm just reading Matthew Syed's latest book - Black Box Thinking - which looks at how different organisations and business consider and react to failures.
The airline industry is by far top of the pile on how it investigates failures and this is shown by just how safe flying now is. Whilst the pilot may be the person responsible for the flight, in any accident it is often a number of errors which compound to give the pilot the job of trying to sort it all out in a pressured situation - the investigation looks at everything to see what failures lead to the problem and how they could be mitigated.
Aircraft running out of fuel whilst the pilot and engineer try and sort a landing gear fault. Despite being told fuel was low they became obsessed with landing gear and ran out of fuel. It was in fact a faulty connection, the wheels were all down and locked in place.
There are now new procedures for landing gear fault lights. Flying an approach so ground staff could check if the wheels were down was the obvious first step, but back then this wasn't even in the procedures, neither was landing with one wheel not down - you'll damage the plane, but chances of survival are higher than running out of fuel and hitting the ground at 200mph!
Syed then contrasts this with the health service - UK and US - where senior staff are still deemed untouchable and failure of systems and porcesses is rarely acknowledged as the reason for tragedies.
Well worth a read.
