This could be huge http://seattletimes.nwsource.com/ABP...2003889769.pdf Hmmm. A retired employee who worked for Boeing for 46 years claims to know more than the FAA and Boeing about how planes should be crash tested. He concludes that composites are not as crashworthy as metal, but does not back his assertions up with any hard data. His complaint is that composite materials are stronger in some directions than they are in others, that cracking is less visible, and that composites are more subject to fire and more vulnerable to lightning. He points out that g levels in a crash are unlikely to be uniform all along a composite structure. All of this is true, but he seems to be alleging some sort of Boeing coverup of these facts. He discounts actual experience with other composite aircraft, saying that either they are not airliners subjected to the stress and number of flights that airliners get, or that the numbers of such composite aircraft are too few to be statistically significant. Of course, his report will make great fodder for trial lawyers when the first 787 crashes, no matter what the actual cause of death of the passengers is. Weldon seems to be down at the site trying to tell people how to crash test an airplane even though he no longer works there. No doubt his experience is valuable, but he cannot possibly be aware of everything that Boeing is doing to mitigate these problems and Boeing is certainly not going to give corporate secrets to former employees. -- Waddling Eagle World Famous Flight Instructor |

My dog knows more than the FAA about aviation. I don't know what you have to do to get fired from Boeing with 46 years of seniority, but it's a LOT. According to today's newspaper, he allegedly threatened to hang his manager on a meat hook, and supposedly made some sort of reference to a noose. He's denied the noose comment, and claims the meat hook reference wasn't a threat. Ron Wanttaja |

Well I don't know about Boeing but in the FAA just being a white male will get you ostracized and run off. Also, if you fail to "Kiss the Black Ass" you will also be run off from the new FAA. Experience means nothing anymore. Politically Correct Tyranny and Diversity ass kissing means everything now in our twisted society. Maybe his boss was a diversity experiment that was technically clueless and he stood up to the idiot? |

The questions he raise are all valid. The public (including us) simply assume that the relevant crash worthiness and fire worthiness results have been thoroughly studied and found to be adequate. I am assuming that Boeing has the answers to these questions, but if they don't, this is the time to be asking these questions. I have personally witnessed the post-crash fire of an experimental Velocity. When the fire was out, there was nothing left on the ground except some metal parts from the wheels, avionics and control links. All the composite parts had simply evaporated. It was unbelievable. The two occupant were taken with severe burn, but I never found out whether they survived. I also personally know of a pilot who experienced a lightening strike on his all-composite experimental airplane. There were some burn marks on the airframe, and all his avionics had to be replaced. Although there did not appear to be any structural damage, he was saying there was no way of checking if there are any internal problems due to delaminations. We assumed that production models probably use an embedded wire mesh to discharge the current. |

The two occupant were taken with severe burn, but I never found out whether they survived. And they'd have fared better in an aluminum airplane? Why? -- Dan T-182T at BFM |
