3. However, as more and more aircraft, like the upcoming Boeing 787, whose whole exterior is made of non-conducting composite materials take to the skies, additional design effort and testing must be made before certification authorities will permit these aircraft in commercial service.

4. The automatic deployment of the ram air turbine maintained the necessity of hydraulic pressure to the flight controls, so that the pilots were able to land with only a minimal amount of damage to the plane, and minor injuries to only some of passengers.

5. When subjected to cyclic stress, the fibres may tear off the matrix, the layers of the material then separate from each other – a process called delamination, and form a mica-like structure which then falls apart.

8. The use of smoke holes or misting systems were also examined and accepted.
