i think GET OUT is misreading the topic here. they are thinking about the portable o2. we are talking about the drop down o2 here. you cannot disconnect the tubes from the generators on this occasion, they are fixed to the generator, and cannot be removed
Actually GEAR DOWN I am referring to the drop down masks and yes they can be disconnected. I have seen the drop down masks and how they connect (we had a spare one on board an aircraft last year to use with the demo kit as the demo mask was damaged, this gave me the chance to see how they connect up).
