All modern fighters are fabricated from advanced composites. The lightweight yet strong primary structures on these plane enable them to turn on a dime and carry more payload. It is only the cost of carbon fiber composites that has prevented them from being used widely in commercial aviation. We are not talking about cheapo plastics found in a toy store. These plastics are safe and have known failure modes.
Its different, military airplanes are designed to go kill and come back and their safety is less of a concern than an airliner. The main problem of carbon fiber on an airliner is when water penetrates between parts and freezes, the carbon fiber will start cracking. All the people that are in the know and I am one of theme will tell you that, and they will also tell you that Boeing is incapable of addressing that problem and they never did. I can assure you that batteries and what I am telling you here is the tip of the iceberg for the 787 problems, it will be too long to treat the problem here on this bord.
Time for BA to stop production of composite plastic airplanes and admit that they are not in the best interest of the public's safety. They are only good for the bottom line but dangerous. I would never fly on a 787 or a composite plastic plane. No way to surbvic a crash landing.
