We got invited on Jewel in March. Best bridge tour I've done. The 2nd officer giving the tour was very knowledgeable and the Captain even joined in and took some Q&A.
When an article starts out with strong words like "shockwaves" then has absolutely zero detail or specificity to the problem and uses "unnamed sources" well, I'd like something a bit more specific.
I'm still waiting for a report on this other than Financial Times to provide some real detail on the issue, not some reporter throwing out words like "shockwaves" and getting the likes of Jim Walker all excited.
That's not true. Faulty doesn't mean ineffective nor does it mean it's an emergency replacement. There are a lot of "faulty" parts on a typical airliner but safety isn't compromised.
What it doesn't say is why they were faulty. It could be something as trivial as screw holes too big and generally unrelated to the fireproof effects. But for a new build, it complicates things due to the strict certification aspect.
They do this all the time. It's a backup plan for last minute cancellations.
I once won a RU for a cabin that wasn't available only a week prior to the cruise due to a last minute cancellation.
