Have often wondered about the rubber jungle. Are there not different types? It's usually chemical reaction produced O2 in this type for the pax right? Are all the masks in the jungle spilling oxygen from the moment they drop? What's the briefed "pull sharply down" action for? Doesn't that start the flow in some systems?
Just found this in the other thread:

Think there is a mask in toilet as well. no masks for so called cue.

So is there a chance the spares in the rubber jungle may have been exploited by a number of people who knew how they were triggered (or not triggered yet)? I remember early (still unsubstantiated?) reports that there seemed to be evidence of a number of conscious passengers at the end. How many spares this flight? Was this 733 configured up to 149 max seats plus JAA mandatory min 10% extra masks or was it the earlier 128 max seats plus min 10% extra masks? So in a 149 config you have perhaps 50 separate pax oxygen triggers and if Pointer is correct you could have as many as nearly 200 total masks in the jungle for the 121 on board?
