EdStainless,
My recent personal experience was a bit different than yours. I recently spent a couple months working for a mid-sized aerospace manufacturer designing some fracture critical forgings for the cryo fuel system on a NASA manned launcher project. The reason I took the job was because it offered me a rare opportunity to work with some of the industry's most experienced engineers, analysts (including fracture mechanics), and manufacturing specialists (in areas like heat treatment, welding, metal forming, NDI, etc.) on a project that demanded the absolute highest level of product performance, quality and reliability.
Although the job paid a bit less than what I would normally earn, it was a fantastic learning experience. Whenever I had free time I would go out to the manufacturing area and politely ask the guys working there to explain to me in detail the particular process they performed, which they were always happy to do. I learned first-hand about almost every process involved in manufacturing these world-class cryo fuel system products, including critical ones like welding that required constant oversight by the metallurgist.
This experience by no means makes me a metallurgical expert. But in just a couple months working at this job I probably accumulated more practical knowledge of the manufacturing and engineering technology involved in producing critical metal cryo fuel system components than one would ever get from a university program.
