Ok, for everyone talking about vaporizing instantly instead of having the time to "burn", consider that there were a great many moments of time "slowing down/standing still" Many elements, and even direct mention of individual/crew epiphany... You even have the embodiment of an antigonist claiming to have directly conversed with "God".

Has anyone bothered to consider the possibility that this scene was meant to be shown in SLOW MOTION, rather than REAL TIME, to add a much deeper meaning to it?

As others have said...it is a Fictional drama, not a documentary.
