Yeh - it only took them three years to get around to doing it. But at least they did it straight after the first signs of it failing on them!
They are a safety conscious mob after all. I think they were a bit harsh on themselves by referring to it as a 'significant event', when really they could have gotten away with passing it over as a relatively minor event and that no passengers were ever in danger because the crew are highly trained to deal with these sorts of things. ;p
Bo!
