David, nice of you to preserve those old warbirds. Hopefully young folks will learn something useful from them, not the glorification of war but it's terrible cost, to be avoided if possible but we still need to be ready to defend our nation if peaceful solutions evade us.
I didn't have an airline pilot dad, mine was a WW2 vet who worked at the VA while working on a pharmacy degree. He had to drop out in his 4th year and never got to become a pharmacist, made a better living for a while at least as a "detail man". I paid my own way through college while driving truck, tried to enlist but couldn't pass the physical due to congenital disability. I can point to statutes I wrote in the law books and helped start the first dislocated worker program back in the 80s.
And while I love restoring old vehicles and have some completed and in the works projects in my shop, restoring warbirds is pretty much a boys club and while I probably learned enough to pass ground school before I could get a driver's license, I could never afford flight school. So no point in my switching from ground to air in my 70s even though I could now afford it.
