Rolling Circle:
The Eye report is lacking in the facts. The aicraft in question was scheduled from LGW to JER and diverted back to LGW. The CAA quote though is, as per my understanding, quite correct.
Raw Data:
I agree that this instance had nothing to do with the ongoing fumes argument on the 146. Smoke / fumes in this case most likely were from a bearing failure (probably no.'s 1,2 or 9) which subsequently spat oil into pack 2.
I disagree, however, with your comment on oxygen - communication is all very well in the sim but imagine a real environment with engines at proper volume, MWS warnings, checklist being read, communication with cabin crew, pax etc. etc. Somewhat different I'm sure you'll agree.
