I haven’t been able to find the actual report yet, but this fits in well with we know. Whilst a cigarette fire in its own right probably isn’t an event, it makes sense as a flash point for an oxygen fed fire. And once anything caught fire and had oxygen venting on to it, you’d have a completely untenable situation in seconds.
The article claims that the mask was left at the emergency setting by maintenance. I can’t see that for a couple of reasons. Firstly a mask test is part of every preflight, so the test would either have to have been omitted or done incorrectly. At that point, a mask in emergency makes quite a bit of noise, so you’d hear it. It would also deplete the entire oxygen supply. A smaller scale leak though, could well go undetected.
This was a 777, but curiously, the same airline. Gives you an idea.
