I must say that considering the number of advisors, secretaries etc available to the committee senators, I'm absolutely appalled at the level of ignorance displayed by senator Heffernan; Most of his questions are cringworthy at best. The hearings seem to be little more than a forum for CEO's to educate the Hon BH about their version of how it is in aviation especially with regard to 'the pilots'. The Hon BH is too ignorant to realize that he's being BS'd by the very people that he should be putting the screws on.
So far it's all been as hard hitting as as nappy wipe at ten paces.
My bet is that the Senate inquiry will conclude that the CEO's, CASA, etc assertions are all very acceptable, the pilots are just having a whinge, safety is indeed at world's best practice. Job well done, now we can all rest assured.
