I was checking all the links in January on my helicopter site and was sad to find that Boeing's website link to their rotorcraft systems section is broken. On the home page of my helicopter site I feature helicopter manufacturers from around the world. It's surprising to me that a major helicopter manufacturer like Boeing would allow their rotorcraft systems link to be broken for such a long time.
I first discovered their link being broken in January of 2011. Who knows how long the link has been broken? I sent Boeing an email concerning this issue in January with no response back to me. Not sure why.
