Disappointing that engineering at the arguably-best transport-aircraft company on the planet led itself down this path - and got it so wrong. Given that, can we trust the objectivity of the 2007 report "Flammability Properties of Aircraft Carbon-Fiber Structural Composite"? (The report specifically examines the composite spec'ed by Boeing, but the work seems to have been done by University of Maryland for the FAA, so the answer may well be 'yes', but it's a pity to even have to think the question.)
