Hypothetical scenario. I'm on a commercial airliner (A320) as a passenger, sitting by the wings. We are cruising at 32,000. The oxygen masks suddenly drop down and the nose pitches down heavily, whilst banking 30 to 45 degrees to maintain positive load factors.
Obviously everyone is panicking, I fit my oxygen mask and realize what is happening. We likely lost cabin pressure and are descending to a safe altitude. In a few minutes, we'll be at 10,000 and can safely remove the masks and land at the nearest airport.
I want to communicate this to the rest of the passengers, to make them feel at ease and less panicked. Obviously the cabin crew are busy helping children and others fir their masks, so don't have time to communicate this, the pilots are also far too pre-occupied.
How can I best do this? Could I take a deep breath with the mask on, remove it to explain what is happening at high volume and then pause for breaths with the mask on? Or maybe I could write it down and pass it around on some paper / a phone?
Any advice would be much appreciated.
