I hear what your saying, some of thier catergories of vegetarian does have seafood. Butter yes that may well be out of the norm but do you know how many chemicals are in margarine, I wouldnt expect a nut butter. I do expect an eatable meal and. unfortunately yet to have a decent vegetarian meal.
You would not be the first one. I haven't heard too many stories of any of my vegetarian friends that have had good vegetarian meals, domestic or international, on almost any airline, in almost any class of service. Sometimes the vegetarian meal isn't actually vegetarian, containing meat etc.. Some airlines don't know the difference between vegetarian and vegan, it would seem. Some of my friends have additional conditions on top of being vegetarian, e.g. allergic to nuts, gluten free, etc.. Sometimes there is no vegetarian meal and basically it was a standard meal with the non-vegetarian parts taken out of it. Some order to fruit meal just to guarantee something appropriate.
Nut butter is something I haven't heard too much of. It's quite viable you could have vegetarian meals served with nut butter rather than margarine; of course, it would be obviously much more expensive for the catering cost, which is probably a disincentive for the airline to adopt it unless it got a large ground swell. On top of that, despite the overprocessed nature of margarine (which may or may not actually be a considerable health risk), until it gets to a stage where it's really bad like cigarettes (and I doubt it will), it'll continue to be offered widely.
So the ovens are heated to 275C which is 527F. Now Ray Bradbury taught us that paper catches fire at Fahrenheit 451.
The oven safe cardboard is not so oven safe.
A rather simplistic assumption.
Book paper, as it were defined in the book, catches fire at 451 degF, viz. autoignition. "Burning" a whole book itself may not see it autoignite at that temperature. The cardboard composition would have a large effect on the autoignition temperature. Being in contact with moist contents or the moisture of the cardboard would also affect autoignition. Autoignition temperatures are calculated at standard atmospheric conditions, which I guess also assumes a standard oxygen concentration. Also, just because you put paper immediately in a space at 451 degF doesn't mean it ignites into flames straight away - it still takes time (though it may be still a few seconds anyway).
All said and done, however, 527 degF is still a rather hot temperature. You can make a calzone at that temperature. Also, the boxes on the outer edges of a given batch would be heated differently to those in the middle of it, it would be assumed. I wonder what Qantas made the boxes out of and how the testing was done - surely some boffin must have tested the heating of such boxes in similar ovens on the ground to check for safety aspects and write the SOP for cabin crew to prepare the meals.
