Etud Iavia,
There has been three fires in 787 fuselage to date with burn-through in two. This is in less than two years of flying and low flying hours, no risk analysis or fancy statistical stuff needed, 'Just the facts.Ma'am, just the facts" as Jack Webb said. Its obvious and clear that a major safety hazard exists on uninsulated (upper180 degrees including the cabin) and possibly on insulated fuselage (lower 180 degrees) and we don't need strawmen categories either.
Isn't it just an obvious, proven and clear safety hazard?
