No doubt, there has been much spoken of the "perceived" collusion between Qantas and CASA in pprune threads.
Whether this is the reality, few would know.
When we have certain contributers, using multiple identities, posting a continuous diatribe against both organisation one does wonder at the relative truth of this perception.
I too wonder at the regulators response to various incidents, but maybe that is because I do not have all the evidence.
