My experience agrees with the OP. Aerospace is sometimes considered a subset of mechanical engineering which is a very broad field that can be applied across many domains. Now if you've spent your career in a very narrow subset of that field and not developed transferrable skills along the way, I'm not sure the fault is entirely the employer's.
