Mine was my dad. He flew for the Navy for over 30 years and I've always enjoyed building the platforms he flew (he's also a great resource for ordnance loads!).
I can remember having a 1/720 or so Nimitz that he had hand-painted the deck markings on, but the rest way bare plastic, with the one-piece plastic planes when I was a kid. I also remember he and I working together on a 1/350 Missouri (I think it might have been the Tamiya one), and I loved getting to work on it. When it was done only the deck (tan) and bottom of the hullk (red) had paint, the rest was bare plastic, and I think I did most of the finishing up. That was the first Tamiya Missouri I built, it was eventually destroyed by the movers. Dad was Navy so we moved a lot. Fast forward several years and I built another Tamiya Missouri, with full paint this time, that was also destroyed by the movers as I am military as well. That Missouri died along with the New Jersey, Bismarck, and Tirpitz in that move. Missouri number 3 is in the stash, but this time I"m going to go for the 1943 camouflage. I still love to build and work with my hands.
Dad has always been more of a woodworker and general handyman (he literally turned an attic space into a whole new room and working full bathroom with no help) and isn't much of a modeller, but for some reason after a childhood of legos, I've always loved building models, particularly Navy ships and aircraft. Both the ones I've served with and his, and then anything that catches my fancy (F4U, B-17, Seafire, an LHD, anything rotary wing, etc.)
