Overtalks theory is most credible....what I find unreal is the temps to go from -46 to -18c in fell swoop....an incredible phoenomena in the ITCZ. An
A330 at its max alt taking weight into account has 1.3g protection.....make the outside warmer by 30c, well theres only one way your going and that is unfortunetly down re aerodynamics. God rest their poor souls faced with an impossible situation.
ISA is -57C at FL370, so this previous event was already at ISA +9. If the temperature was -19C that would be ISA +38C, which is an amazing temperature at altitude.
I've seen ISA+15 or so until the mid 30's. Above FL350-370 it's been my experience that it's rare to get ISA+15.
