Jet2 loss of cabin pressure Pisa to Manchester 9th May

We were on a Jet2 flight from Pisa to Manchester on Thursday when over the midlands the oxygen masks were deployed and we descended to 8000ft due to loss of cabin pressure. We made a safe landing at Manchester albeit with a fire engine escort. The crew from the pilots to the air hostesses were brilliant and there was no panic amongst the passengers. Jet2 had even laid on extra ground crew at the carousels for any questions It was our first emergency incident we have ever had and I was just wondering how rare is it for this problem to occur

" I was just wondering how rare is it for this problem to occur " - I would say very rare but can't find the statistics, glad the crew responded well and you landed safely.

Quite rare.The modern aircraft use onboard oxygen generators in place of the old fashioned large oxygen bottles in the cargo hold.This is a great weight saving option,but the drawback is that it is a 1 use only system,so the oxygen generators need to be replaced after use,which is expensive,time consuming and difficult.

Once the reliability of the pressurisation systems reached the current levels,it is cheaper to use the oxgen generators,but when used the aircraft may be out of service for a few days,so if it was a common occurance the economics would rule out this technology.

The pressurisation system has no effect on the other aircraft systems.It is perfectly safe to fly a modern jet unpressurised at low level.The drawback is that the fuel consumed rises dramatically as the engines are less efficient at low level,and the true airspeed and mach number are greatly reduced.This would meen the fuel required for a particular flight would be increased greatly.

On thing it did make me realise was how the same safety briefing given by all airlines pre-take off has not changed for years, and how it needs to be improved. In reality when the aircraft is flying normally and then suddenly Emergency Procedure comes on and the oxygen masks drop it takes a few moments to take it in . Then you pull the mask towards you but certainly not the sharp tug as is always demonstrated Then, and partly because you're not sure you have activated it, you wonder if it is working correctly as the bag part is quite flat and not full of air as you would imagine it would be. This was probably the most concerning thing about the whole incident. Having now goggled it I now know that that is perfectly normal. We then start a decent to I now know again through goggle to 8000ft, all standard procedure in these circumstances As I said in my first post the crew were brilliant and the pilot kept us informed as soon as the situation was under control and he was then able to. We are not nervous flyers and in a strange way it has actually made me feel even more relaxed having seen first hand how the emergency procedures spring into action and work.

They *always* state that in the safety briefing. Well, every one I've sat through I can recall anyway.

"The bag may not inflate"

Every safety briefing I can remember.

"Oxygen IS flowing, though the bag may not appear to inflate."

Yup, every safety briefing states that specifically.

We’ve sat through hundreds of safety briefings and always ‘Think’ we listen but obviously not, as we have never heard that. It just shows you what you miss but is that mine as a passenger’s fault or a shortfall in the briefing I can only suggest that since you’re concentrating on how the mask fits that fails to register.

I notice the incident has now been picked up by The Manchester Evening News Believe me it was nowhere that dramatic no doubt due as I said to the professionalism of the crew and how calm fellow passengers remained.

I had never heard it before and thought it was interesting that BA did say "the bag will/may not inflate" when I flew them last month.

So what was the reason for the masks being deployed and the rapid descent? That's more interesting/concerning than the crew's behaviour after the event.

They've said the bags would not inflate on every safety briefing I've heard. Around the time they tell you to put your own mask on before assisting other passengers.
