Lets get some perspective back into this thread and avoid the hyperbole.
1. CAA statistics show 167 pressurisation related diversions into UK airports in the last 10 years, about one every 23 days on average.
2. While many may have been only minor and/or precautionary, in each event the crews reached terra firma in one piece and executed both their responsibilities and training competently.
3. The possibility of experiencing some form of pressurisation event is fully and properly recognised by all the major aviation authorities as evidenced in the initial and recurrent training/testing of crews in this area.
4. Structural failure causing sudden depressurisation and further structural / control damage is thankfully a rare event. The complex and challenging complications caused thus can only be partially trained for, and therefore often means crews making fundamental decisons with incomplete information.
Therefore let's freely recognise crew competency in (3) and keep hero comments for (4).
