Offset control locks, and VH-CAN
I flew VH-CAN in a later guise. Although I've handled the locks many times, and can picture them in my mind, annoyingly I don't recall enough detail to remember if the rudder lock was offset. I'm fairly sure the aileron ones were, but the mind is a funny thing and it's a good few years ago so I wouldn't be surprised to be proven wrong - Centaurus, fwiw they were red-painted aluminium channel, just in case they're the same as when you flew her?
Anyway it's a damned good idea. We were always careful with all our checklists and of course they were part of the pre-start list but having some sort of failsafe in case of distraction or whatever is good human factor engineering.
