The point of my posts is that safety in the industry is a matter for the industry.
Now I don't follow you. Safety is a matter for industry in as much as they must meet the level set by the regulator.
There is only one successful way because the UK has proven it over many years. That may also explain why they come across as arrogant at times.
Government tasks the regulator
regulator tasks industry (by producing regulations)
industry has responsibilities and is accountable
key individuals are licensed (pilots and engineers) they are responsible and accountable for their actions
The airworthiness of Concorde was sound as highlighted in post 446 by PBL.
If you want safe flying people must be accountable for their actions.
There is no escaping the downright shoddy, inappropriate, unapproved repair carried out by the mechanic. It is that simple.
Repair done properly, NO ACCIDENT.
