Not one of them has ever worked as an operational airline employee.
Looking at the biogs, barring Cos not one of them has worked as an operational employee anywhere. Have any of them worked at all?
Seriously we have: two lawyers, 2 executive engineers and four beancounters, one airline (Joyce) and one Army (Cos). There aren't even any experienced transport industry execs, let alone aviation ones. Board airline knowledge is presumably limited to finding the Qantas Club and working out how to recline a first class seat without spilling the Grange everywhere.
