OK, I promise. That business with Stewart was a real shame. I always thought he was one of the classiest individuals on the tour.
So, do the oxygen masks in a pressurized cabin only drop during a sudden depressurization or will they also drop when the oxygen level in the cabin drops below a danger level? Having only ever flown non-pressurized small craft, I never really gave it much thought other than keeping my altitude under 10K.
The masks will drop in either condition, sudden or gradual.
