IIRC from years ago the tanks are made the same except for the thread. Any corrosive effect would be due to contaminants like water and care is taken that there is no water in either.

no.nitro would actually inhibit corrosion as it's inert preventing oxidisation.

Out of interest, how many passenger oxygen bottles are there on QF 744's, and are they all located in the one row?
I see the (Australian) Daily Telegraph were well out of their depth when they posted a pic of the very large potable(drinking) water bottles in the aft of the Forward Cargo, claiming that they were oxygen bottles. Someone posted the same pic on PPRuNe the day before, but he did warn the forum that he wasn't sure if these were the bottles in question. Looks like the Telegraph ignored that warning.

And guess where the so-called reporters get it from - here! Plus other places of course.
We should really get our memberships done here based on our licence numbers. But then it probably won't help...Chards

To those wondering about the depress case with an oxy bottle taken out of the system there are portable oxy bottles on board which are there as part of the theraputic oxy requirement. I'm sure that will all be covered in the final report which I don't think will be ready until 2010.

Opinion piece.
It is quickly becoming an empty shell, all that will be left is a brand with everything outsourced. A full service provider without providing anything physically itself. (perhaps contract management?)
Frequent flyers sold?
Airports sold?
Catering sold?
Holidays sold?
Flight Training spun off?
Engineering reduced and outsourced?
Ramp services outsourced?
Most of the fat is gone, and now the butcher is making cuts into the muscle, weakening a once fine beast. The remaining quality cuts left are being affected and demoralised by a brain infected with mad cow disease.
Perhaps it's time to cut off the head? (lots of fat there)
Totally agree with splitpins take on the situation.
Evidence suggests another game plan that's not being divulged to "relevant stakeholders"
Does anyone know if are Airbus and Boeing providing "Total Care Packages" for the A380 and B787 for engineering?

Don't know about Airbus but a Boeing gold care manager in Seattle told me they were backing away from the full line service especially in places like downunder.
He also mentioned facilities in other countries after giving us a presentation that showed their Brisbane location in OZ and many other countries.
Sorry can't tell you any more he refused to give any other info they all claimed to be ignorant of any details other than the marketing spiel on the 787 they were giving us.
Should be a nice plane if it ever gets here.
Hopefully QF BNE heavy maint will get some work it's the only hope they've got

I have no hardware knowlege but I thought from an ATSB / news report that it said the CVR only keeps the last 2 hours or some shorter period than the data recorder that stores the last 24 hours.
So its quite likely the CVR was full of everything they could get.

When was the first C of A issued? Most of the thirty minute recorders that were original equipment in older aeroplanes still meet the ICAO Annex 6 requirement and may remain in service.
The 01 January 1990 recommendation for a two hour recorder was just that - a recommendation. Most operators have specified the two hour recorder for aircraft acquired after that date but very few have accomplished retrospective modifications, especially on leased aircraft.

Bloody cool character that Captain. First thing he thinks of after an on board explosion, emergency descent, and diversion, is, park the brakes, open the door, and press the erase button!

CVR info for the laymen
The CVR records all flight interphone and cockpit area microphone audio (via 4 channels) on a closed magnetic tape loop that overwrites itself every 40 minutes. It is impossible to erase any recorded information while in flight, the tape simply writes over old information due to the fact that it is primarily used to investigate cockpit conversations just prior to an extreme incident (read hull loss).
As a result, whatever expletives were voiced when the oxy cylinder let go would have been erased by the time the aircraft landed in Manila (recording continues even once on the ground until pwr is removed from the aircraft..or AC bus 3 at least). It is possible to "bulk erase" the recorded audio with the erase button on the voice recorder control panel but only once you are in full ground mode (park brake set, no engines running and at least one main entry door open)
Simple

ATSB initial report
Looks like the gas cylinder was most likely the cause.
If you wish to read todays ATSB press release follow this link
MEDIA RELEASE : 30 July 2008 - Investigation into Boeing 747- 400 depressurisation and diversion to Manila, Philippines

So do I take it once that once again this has absolutely nothing to do with QF utilising modern cost effective offshore maintenance facilities for their airframe maintenance?
Where are the bottles maintained?
Internally?

Managers Perspective:
Used to be the case, years ago, however I am informed that this function of QE has also been "outsourced", presumably to the lowest bidder. Will stand corrected if anyone can rebut.
