Re: South Carolina made Dreamliner: A nightmare?

For me it is obvious that the authorities cannot (and it isn't their duty) to inspect every aircraft produced. That's the manufacturer's responsability. So what's going on?

Re: Jet engine combustion chambers

Does that mean that if one cools the temperature of the expanded hot air inside the burning chamber before it reaches the HP turbine (to make it spin) one looses energy, thus wasting burnt fuel? Is that what you mean? (Interesting stuff, btw...)
