Sorry, Raven but aside from being wildly off thread, the Swissair fire was so severe the pilot seats had molten metal poured onto them. What kind of uniform do you recommend for that? Would nomex suits would have made the slightest difference? For what it's worth I've yet to come across an acrylic or nylon airline uniform. Most are a wool mix which, while by no means fireproof, compares quite well in terms of fire resistance to the pre-nomex issue of RAF suit.
