Nice to see so diverse fields on this group!
I'm a designated "Software Specialist" for an aerospace engineering company. We are a joint venture with Pratt and Whitney. I basically work on 'controls software' for a few Pratt jet engines. I actually studied Computer Science/Math but somehow ended up doing Engineering work here which is both good and bad (i.e. I don't know how to program for sheeeit now and at the same time I don't have an engineering degree so... weird Limbo... lol)
