gord- 'Safety wired' or 'witness wired'?...in the Canadian Air Force
'safety wiring' is to prevent accidentally flipping the switch
guard up and flipping the switch. It takes (even more of) a
deliberate action to activate a switch. BRBR

Safety wired the cover down so you could go to 'training/test' but not 'master
arm on'.

It wasn't a thin copper wire, it was a big piece of steel safety wire. It was
to prevent anybody from arming any misslile when in peace time. These would of
course go away as soon as we were honestly 'warning yellow or red'...
