After reading the various postings on this thread and many of the sub tier documents referenced in some of the postings I now have an understanding of why I majored in Industrial Design instead of Engineering. Although I do not possess an Engineering degree I have a detailed understanding of space craft, weightlessness, rocket engines, ballistic missiles, aircraft systems and helicopter systems as well as ships and other military systems and systems used in civil applications. True, I don’t fully understand the detailed engineering that goes into the design of some of these systems but I do have an appreciation of those engineering requirements and I have enough of an understanding relative to how these systems were designed to work and those elements that keep them from performing according to specs. So, based on that understanding of my limitations I will cease adding to the confusion and the possibility of highjacking a thread unless I am driven to it.
