[SystemSafety] Comparison of Confidential vs Non-Confidential Reporting Systems

There's another layer to it as well - from society's perspective: the visibility and nature of the victims of accidents. Aircraft accidents are very visible, and the people who are impacted by accidents tend to be wealthy. I'm sure some of the biases mentioned in the "Bounded rationality or ignorance?" thread come in to play as well. The end result is that there is far greater social pressure to achieve safety for aircraft than in mining or shipping for example.
The result is that aircraft industry has a very broad safety culture, spreading across the aircraft manufacturers, the airline operators and the government authorities. The breadth I think enables working practices (such as reporting) that would be difficult to sustain in a more fragmented safety culture in other sectors.
As a comparison, I was very surprised by the personal risk associated with medical procedures that are accepted as normal and the risk associated with flying - In medicine it appears to be accepted that the safest procedure under general anaesthesia will have a 1 in 10^5 risk of complications resulting in death, whereas taking a flight is around 1 in 10^9. You could take 10 flights a year for your entire life and still carry much less risk than a single operation. It's hard to tell whether society has its priority straight on this.
Cheers,
Alvery

I’m thinking historical reasons, from a Lindbergh biography by A. Scott Berg I read years ago.
Aviation in the US was funded by the government for air mail. To save money Inexperienced army pilots
were recruited and started dying from accidents in high numbers. Lindbergh, promoting flight safety called
out president FDR’s actions as the cause for their deaths. Safety regulations then came into force,
but by making FDR angry, Lindbergh (an ex-Army pilot and also an America First-er) was prevented
from re-enlisting as an officer during WWII.
