I'm jealous, you have over 20 years of working in aviation, and the hardest thing you've had to do was change a light bulb... No, but seriously, I'm jealous, a good/interesting job that's involved with aviation, can't get much better imo. 
I wish it was closer to aviation than it is. I just get to see what lights them, inside and out, tip to tail. I never get to be part of the install, we ship our products and the customer does all that. Though I did have to go to the Lockheed plant in DFW once, and that was quite awsome to see our lights installed on the F-16 up close on the production line.
