It's a good idea to find something other than aviation, sad to say. Medical test equipment ought to be made for a sparky like you. The current wave of good times in the commercial aircraft business will not last. I went to A&P school in 1980 with a guy who was a UW Aeroonautical engineering grad and he was from Snohomish County where his old man had a dairy operation. He well remembered the signs on the freeway that said "Would the last person leaving Seattle please turn out the lights?"
I myself went through the last aerospace deconstruction in the early nineties. As a 40 something A&P I asked myself "What part of this do I want to repeat?" and I went and finished my BA
and got a law degree.
Of all the people I met in the trade, I can only think of two people who successfully dodged all the layoffs, and they have not yet made it to 65. On the other hand, Steve worked as a roustabout in the oil patch up near Rangeley Colorado and got his collarbone broken and lost his job. He said there was nothing worse than being out of work, unable to work, and winter coming on.
