I had only one depressurisation in my 40 year career and that was not sudden, merely a gradual loss (air supply valve or something like that).
Unknown to me, I had a senior (non-flying) member of management on board. A few days later, I received a call (with a follow-up letter) from my line manager that was of a very unusual nature. I had apparently got a pat on the back from the senior passenger "for the reassuring way" I had handled things. Normally a call from my boss was to the effect that (again) I had upset some young stewardess by being "too abrupt".
Unfortunately, I never kept that "green" letter as it would have framed and been given pride of place in the downstairs loo.....
