WHAT HAPPENED TO CAUSE THE DECOMPRESSION?
Having waded through 7 pages (of which the usual 90% is utter rubbish) no one has yet said what caused it!
To those passengers who do listen carefully to the Safety Brief, well done. May you and your loved ones always fly safely. And, just to reiterate, if the masks drop when you are in your seat the action of moving the mask to your face will be enough to get the oxygen flowing. You may however feel a slight resistance in doing so and a gentle tug will do the trick.
To those of you who can't be bothered with the Safety Brief, and I include those who think they know better (particularly carbis22 who has shown himself to be a complete @rse!) maybe you can learn something from this. Just remember that the crew (both flight deck and cabin) are very highly trained professionals who, in any emergency situation, will be doing just what they have been trained to do. Remember also that they are as keen as you are to get home in one piece.
