Northrop YF-23 Production Version Proposal Drawing

 I was a configurator on the Northrop YF-23 program and was one of the designers of this aircraft.  I was responsible for the GE engine Version of this drawing and all the associated  CAD models.  This project was done on a mainframe using Northrop's NCAD for 3-D wireframe modeling, NCAL for lofting, and CADAM for the 2-D drawing.  A cumbersome process by today's standards.
