I think there is a danger of pitching it as affordable safety as it gets spun into cut price safety by those with other agendas and makes the whole debate about money and misses the point of what serves what.
Aviation provides a net benefit to our nation and safety underpins the viability of the industry, not the other way around.
We need safety to be effective and appropriate or the industry suffers as does aviation's communal benefit.
Appropriate and effective safety certainly means managing cost but also means maximising convenience and minimising loss of benefit. Bang for buck. Not all bucks or all bangs.
