Caa review
If we accept the caa review at face value, it will be limited by their legal remit to questions of aviation safety (though they will look at ditching and survival - see terms of ref). Other, wider, issues are raised about the offshore working environment and unions are rightly emphasising these in the Piper Alpha memory year - the emotional level is understandably high.
We can't ignore the uk accident history, but with 3 recent gearbox failures which arguably might have occurred anywhere in the world, that seems to leave blun, etap & the latest (plus poss cormorant alpha?). Is there a common theme different to anywhere else?
