Well done to the crew of this flight, it was close to suitable airports on this route, but what if the incident happened on the soon to be SYD-EZE route, which the great circle track takes the aircraft around 2000nm from the nearest suitable airport?
What is the endurance of a 744 at 10000 feet?

The Bright Side To All This
1.No One was Injured
2.The Fellows in the Cockpit performed admirably.
3.The Cabin Crew likewise performed well.
4.The hull is intact and will fly again.
5.The event did not occur over the Himalayas.
6.Best of all...this whole bloody mess is what that vertically challenged R Sole Dixon will be remembered for.The treatment of LAMES over the last couple of months has been both immoral and reprehensible.Dixon will leave on a low note...aas he deserves.
To the entire crew of the QF 30...an outstanding result!!

Every flight plan calculates all contingency range configurations including engine/critical systems failure and depressurisation. The SYD-EZE route will be planned in accordance with CAR's, CAO's, AIP's etc and the route will be such that the aircraft will have sufficient range to divert to a suitable airport at all stages of the flight. Some posters on this thread have commented that it was lucky that this event did not happen on the previous sector wrt high terrain adjacent to the Tibetan plateau. Every segment of that route has been analysed and "Escape Procedures" have been published (& which both pilots at the control seats have in front of them) to take into account Single Engine Failure, Two Engine Failure and Depressurisation cases. By law, RPT operators are required to comply with these requirements and at no stage is an aircraft going to caught in a no option situation.

To Leigh Clifford and The QF Board...
It is the people who work for Qantas who are Qantas.
It is not the opportunists who masquerade as management.Those whose prime motivation over the last ten years has been the creation of executive wealth.
Mr. Clifford when Dixon leaves you will have an opportunity to do something that the current managment have failed to do.
Rebuild Qantas back into the premier/premium Airline that it deserves to be.
Dont Phuck Up this Golden Opportunity?
Everyone in Qantas will be behind you in this endeavour.
We have been waiting for a long bloody time.
You have what Jackson didnt...balls.....use them.

Just a thought. The media is going on about oxy bottles letting go. But that far back in the cargo there are no oxy bottles, but there are cargo fire bottles.

Page 747.6.1 shows the location of the oxy bottles relative to R2.
PS - Big file!

Decompression
Seems the hole was caused by a failed Oxy cylinder BBOOOMM!!. They are stored along that side of the fwd cargo and contain O2 at about 1720 psi. QF sent a team of specialists well 3 anyway - A LAME and 2 Sheeties plus they were outnumbered by "managers". Lucky it wasn't a dinosaur as the oxy bottles in those are in the cargo roof which is also the cabin floor. Also ALL the control cables run above the cargo. Good ol' GD sacked all the guys who recovered OJH and could have recovered this one too. Looks like it will have to be out sourced perhaps to Boeing. There are reports from locals that there is significant structural damage around door 2 R from the initial explosion and decompression.
Any one know where the O2 bottles are overhauled, OS perhaps?

Keep scrolling Anti splash it shows -400 too. But it is not a very good image. Qf 400s have the extra bottles installed to allow flights over the himalayas, this image does not show the full number of bottles that can be installed.

I've copied this from the thread on R&N... just to pre-empt the comments and questions which may otherwise appear...
It seems pax are now saying that the oxygen system failed (at least at some seats). Just a thought here that it may not have failed but that pax are required to pull the mask down for it to work, and unlike other aircraft which use the chemical oxygen generators, activiating one mask on the 744 will NOT activate the entire row.. so maybe the 02 didnt fail, maybe the pax just didnt know how to use it properly??

B747 300 & 400 Pax Oxy
Pax oxy sys on this aircraft, as stated previously, is of the 'stored gaseous type'.
Pulling down on a mask will activate o2 flow to THAT MASK ONLY.
Therefore, if pax are too shocked/innattentive to briefing to REMEMBER this, they may NOT have pulled down on their mask- if it was flapping in front of them my guess is they'd remember the part to grab it and put it on- but possibly forgot the part of "Pull down on it firmly"" in favour of put it on quickl˙, and ensure the strap is tight"
Most pax wouldn't know what a flow indicator is or how to check for oxy flow. (In this case, bag MAY inflate)
Flow can be shut off at individual units/masks when no longer required. Duration would vary on time of descent, number of pax, demand etc...
Yes, flight crew also have backup in the form of a portable bottle similar to those seen worn by the cabin crew in that video.

If the bottle is missing, did it cause the decompress or did it simply get sucked out when the decompress happened. If they are able to find the missing bits it would go a long way in solving this problem. That, however, remains unlikely.
Contaminants need flow or a shock to cause problems, just sitting there is unlikely to cause you any problems until you need to use it or you do maintenance. A latent time bomb.
Anyone remember A9-300 1984?

i think the best thing to come out of this is the FAA and NTSB. I wonder if QFE management are as friendly with them as CASA? maybe we might hear some resignations soon if this thing turns out to be maintenance error. GD and DC better get there cards out and start shouting dinners!
