The Smiler 

I was reverting it to what it was originally but made spelling mistake puting SNBO instead of SBNO: my last edit to fix that typo accidentally went over someone elses S

Anyway
I agree with what was put there originally: SBNO. It cannot be put as testing as we have no reference to say that is being tested. Standing But Not Operational describes exactly what we know: its standing and it's not operating. And there are 3 or 4 references in the delayed opening section of the page which cite that information: that it is finished and not operational.
