I've actually been thinking about this for a while. Would start my own foundation and buy a bunch of warbirds, flying/static displays and build a museum hangar co-located with one for me. Would be cool to get that F4 on controller for a half million. Flying it/upkeeping it might be a different story. I feel like it would be reasonable to maintain insurance and fly 1 or 2 of the warbirds each year, maybe alternate which ones, but maybe it's way more money than I'm even imagining.

In my state, it looks like you'd end up with 240 million after taxes. I figure the total I will be left with after donations, sharing with friends/family, and buying everything I could ever want would conservatively be 150 million. Still being conservative, assuming a 5% return on however you invest that would give you 7.5 million a year. Call it 3.75 million after taxes and everything. Now here's the thing, from what I've read the cheapest jet you can get into is the vision jet for 3-3.5 million. Astonishingly the operating costs were quoted as a half million a year. I haven't looked at other jets much, but if they are running a similar ratio of 1/6th of the purchase price as their operating cost, I'm not sure I'd be comfortable buying anything more than a vision jet. Like I know you have 150 million in the bank, but conceptually spending a 6th of your yearly income or more on operating a jet seems prohibitively expensive, even at that level.

Maybe I'm just too poor to understand, but it's fun to play these scenarios out!
