In the safety instructions, one always hears of the possibility of depressurization of the aircraft with oxygen masks coming out.
Has such an event ever occured to you. If yes, we you told the reason for it and wahat was the general atmosphere on board ?

One time I was flying an AS MD-80 from SEA-ANC, this was about 1995-ish. We took off and flew for about 15 minutes when the pilot told us that the planes pressurization system failed. we were probably at about 10000-15000 ft. i noticed no difference and no one needed any medical assistance when we landed.

Quoting NWADC9 (Reply 4): All the time! Otherwise there'd be some serious issues when the door's opened at the gate
I think you will find that to allow the door to be opened at the gate, the cabin has to have been pressurized from what it was at cruise.
Have run the cabin height up to about 20,000ft on a test flight, using supplementary oxygen, and it seemed OK, but there again I was just sitting down. Found it to really interfered with the smoking though
On climb out of Entebbe once had a short on the electrical bus bar which controlled the pressurization, so closing the discharge valves, and for a short time the cabin went down the mine. What made it worst was it was at night and the cockpit main lighting came off that bus bar too so we were in semi darkness

Am I right in thinking that Ryanair's old B732 aircraft were not allowed to fly any higher than 22,000ft because of pressurisation problems? I flew MAN-DUB on one and it felt like I could hear air rushing in through the gap in the cabin interior, not a good flight but I didn't notice any problem with the pressurisation even though we were at a restricted altitude.
...love is just a camouflage for what resembles rage again...
I was onboard cleaning the aircraft for the next flight and the crew just got onboard and was preflight-ing the cockpit... I heard the PIC ask "What the hell is this switch set like this?" He must have bumped it or flipped it or something, then all the masks came down...
