The fuselage of the jetliner involved in a collision on a Tokyo runway was made from carbon-composite fibers, and the incident is renewing concern about the challenges of putting out fires involving the material.
The fire is shaping up as a key test of the safety of composite materials compared with conventional airplane fuselages made of aluminum.
Safety experts are praising the airline’s crew after everybody was able to escape the burning jetliner. Five people on the coast guard plane were killed.
Composites have been used for many years inside commercial planes, such as the floorboards and other structures.
Boeing built the first commercial plane with a fuselage and wings made from composites reinforced with carbon fibers, the 787. The plane went into airline service in 2011, and about 1,100 have been produced.
