Have Your Heard This From Your Metalcaster?
In our experience, metalcasters aren’t a smug lot. Reserved maybe, but not the type to rub it in when you get something wrong. Of course, they may have a hard time biting their tongues if they read about what Boeing has been up to. According to the Los Angeles Times, the aircraft manufacturer is late and over budget on its 787 Dreamliner at least in part because of components it has outsourced to overseas companies. The article says managing foreign made con- tent has turned out to be more diffi cult than managing in-house pro- duction, and many of the suppliers with which Boeing has contracted have turned out not to be able to produce the parts with the level of profi ciency they claimed.
