ryanair depressurisation
I have posted this before with the Qantas incident, but I believe it is more relevant now.
Cabin crew should include in their safety briefing something like: "should cabin depressurise, oxy masks will drop and the pilots will immediately carry out a steep controlled descent to an altitude where air is more breathable. No need to panic as it is part of the pilots' training and regularly practiced by them.
I was never a happy passenger, but now that I have a son flying for an airline, one or two conversations with him have put my mind at rest.
People fear the unknown and the unexpected.
