As far as the A380 goes, it has pretty good altitude capability
And what would it's altitude capability be with one engine out? And what happens with a depressurisation? Oh that's right, QF planes are so good that they never have engine failures or depressurisations. All those incidents over the last 5 to 10 years were figments of my imagination. We account for terrain with an engine failure and/or depressurisation throughout a flight. Are missiles less of a threat than terrain? Perhaps they are not a given like terrain is, but where do you draw the line?
But it seems that the QF management are no the only delusional ones -

Now we have the situation where not only the public think that government will keep them safe, management believe it as well. What hope do we have?
