Ozexpat,
Like your style, and you're probably right. Hopefully the obligatory home video will survive and make it to Funniest Home Videos!
Thermostat,
When you say there's as much O2 at FL390, are you talking volume? I'd assume that there's much less mass. Would the reduced mass have any bearing on the sustainability of a fire?
Tcas,
I guess it goes without saying that one of the considerations re depressurising would be the necessity to deploy pax and crew O2.
