Fenland 787,
I said that self ignition temperature of the Toray 3900-2 resin is 580 degrees F not 540 thereby releasing dreaded FST. This is from Toray, FAA and Boeing, so don't try and spin, it won't work. It is flammable, end of story, and top half of 787 is not insulated via Boeing lobbying of the FAA asi stated a while back.
Defending the indefensible is neither pretty nor useful.
