That assumes, however, that there is a means available of mitigating the risk or the consequences. Just knowing it could happen and being ready doesn't help much if, for example, there isn't enough elevator authority to counter a full stab runaway, and you don't have a reliable means of turning the stab off. The fact that they are allowing ferries presumably means that some mitigation has been defined, perhaps with specific procedures or limitations.
