The "buck stops" where?
Without wishing to seem too "Islamic" about this, if everybody had stayed in bed, someone was late, or an engine had failed to start on time, the crash maybe wouldn't have occurred either. If that will, then it be done.
CAsA prosecuted Transair, not Aero Tropics despite the fact that the aircraft had Aero Tropics written down the side, the tickets were Aero Tropics and the flying public believed it was an Aero Tropics flight. This can't be likened to a code share and is a blatant disregard. CAsA were aware, I'm advised, of at least one previous incident in the weeks prior, yet nothing appears to have been done that could have played a role in preventing what eventuated.
Phelan once said, who's watching the watchdog?
CAsA do have blood on their hands I'm afraid. They failed in their duty of care to the public. They failed in their duty to the crew. They were either asleep on the job, or were too busy watching a protected tree, they failed to see the unprotected forest.
