Procedure : emergency decent x 3 over the PA. Get the A/C down to 10000´
or MSA. Evaluate situation, oxygen mask´s off, communicate with the No. 1 a...n..d then make an anouncement. What´s this bussiness about talking to the pax on what´s going on in the middle of an ´rapid decompression´. The ear popping´is normal in a decompression ie. severe ear and sinus pain, feeling cold, chest and joint pain caused by nitrogen bubbles in the blood expanding, forced expelation of air. As someone mentioned if, you as a pax paid more attention to the saftey briefings then you might be more aware of what´s going on in this type of situation!
The cause of this particular incident well...as usual, wait for the report. Needless to say a very uncomfortable situation for all involved. But, by the looks of it, a well execute procedure!
