The difficulty with raising a civil aviation safety issue (in any context from yours to inside design or regulatory offices) is that civil aviation is statistically very safe.
Given that flying is inherently dangerous, the fact of this safety is remarkable - indeed I don’t think it has a parallel in any other risky human activity (surgery, road travel etc).
However a TV programme that investigated what lay behind the safety - not the risks - of air travel would clearly not attract many viewers among the general public.
So you have a problem with balance.
How about this for an angle:
The safety we enjoy today is the result of the inherent risks of aviation having been very well dealt with in the past by all concerned (designers, regulators and operators) and there is no reason to suppose all aspects of this successful endeavour will not continue into the future. BUT, and it is a big BUT, there seems to be a NEW safety THREAT emerging which only arises BECAUSE of this successful past which has allowed civil aviation to become a commodity in the literal sense of the word. This commodity is in danger of being exploited by managers who are too young to remember when aviation was not safe. These people (perhaps rather naturally) take safety as a given and just try and improve the bottom line by cost cutting
Enter the threat of crew fatigue…………………….
