Originally I and others were working with the assumption that the crew realised the pressurisation problem and that their O2 system had been compromised in some way, but the report makes it plain that that was not so.
A common thread of the non-fatal pressurisation incidents discussed in the report is that the cabin crews did not let much time elapse before raising a fuss when there was no descent after the rubber jungle came down.
And it does raise issues of training and SOPs on both sides of the cockpit door.
Perhaps we need something a bit more obvious to let the flight crew know the rubber jungle's about to come down or has.
Maybe the crew oxygen masks could pop out? Provided of course that they stay within reach.
In the interim, how about hanging a balloon off the overhead panel
More likely this scenario will be included in the recurrent training syllabus if it's not already there.
