PJ2:
how will, if shown to be the case, will "the killer items" be dealt with from here on in?
I think I know where you are going with this. It is apparent from earlier posts by highly experienced pilots such as yourself, that the three killers at TO are already informally re-checked again immediately prior to takeoff. Given that confiuration related accidents are far from infrequent, would it be desirable and/or feasible to formalise this final check?
