I do not think this is true. There are certainly some vernerable designs for airframes--for example the DC3. Nevertheless, aerospace continues to make strides in propulsion, avionics, materials, and the design process itself. _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
