Wow! - Eddy what a deeply worrying response to a not very deeply worrying situation!!
Perhaps you're right and, assuming that you are cabin crew, both you and I know better than to think that there is any real link between the cabin being so terribly cold and the potential for the aircraft to be involved in an accident.
HOWEVER, the press carried stories about the Helios crash which clearly made mention of the cold cabin. Joe Public or your average nervous-flyer might not be able to see the situation as clearly as we can.
