It's tiring, but we'll press on.
And to put some balance into the assertion that Boeing don't require it, that's because FAA require it in the majority of transits, unless there is a specific dispensation given for a particular outport, which then needs to be carefully assessed, before the Operators Ops Spec is amended to allow a pilot preflight only. In conjunction with that, the engineering preflight both before and after that outport is also amended to include more stringent preflight requirements, for instance tyre and brake wear etc.
