In the last 50 years, on western civil aircraft, how many sudden cases of loss of cabin pressure and subsequent application of 10-20 sec of TUC? Now consider the number of flights where it did not happen. Then consider the total flight time of all flights globally and put it in relation to the total time of a long haul flight with an inexperienced SO alone in the seat.
I think Magenta is not far off, less than one in a billion would be my guess.
