That's all very well intentioned comment Captatain Stable, but what about those poor pople in the back who are blissfully unaware of how clued up or otherwise their Flight Crew may or may not be regarding the potential issues.
It may be "more fool you" for those in the drivers seat if they don't do the homework but for the 120 in the back it's a bit tough?
Is that the point you are making?
