Slightly depressing topic. Why don't we just talk about when a giant meteor might slam into the Earth and wipe out all the warbirds?
OK, on the serious side I really don't think it's as bad as all that. While there are still many WW2, Korea and Vietnam vets who fly warbirds, there are just as many who, like me, came up from the J-3 cub ranks (40 years old and grew up at the airport) and never got the opportunity to fly in the military.
It was the return of WWI pilots that kicked off the barnstormer age, and it was the WW2 vets who really got the ball rolling on preserving warbirds in the 50's, 60's, and 70's. As these vets retire and prices increase the warbird ranks are now being filled by the only people left, namely business owners and entrepreneurs. Well, who else? To fly a warbird you have to 1) Be a pilot 2) Have the time and ratings required, which doesn't happen in a year or two, so business flying is a plus 3) Be able to afford to buy the plane 4) Be able to afford to fly the plane 5) Be able to afford to maintain the plane, and 6) Often be able to self insure the plane. Think about all that the next time you hear someone sprout off about "rich yuppie" warbird pilots who just want to walk around in a flightsuit.
Trouble is, warbirds are expensive. They're expensive to buy, expensive to fly and expensive to maintain. Insurance is a problem, as is the increasing price of engine overhauls, availability of spares, trained mechanics, the ever changing requirements of the FAA concerning training and proficiency. But in spite of all this, warbirds will continue to fly. They will be safe for the next generation because owners do it out of a love and pashion for these aircraft and the joy that comes from flying them, and hang the expense. Just don't tell my wife.
So don't worry, warbirds are not going anywhere. From Microsoft's Paul Allen buying everything under the sun to the guy who decides today is the day he's going to step up and buy a Yak or L-19, to the guy who helps wrench on some project the warbird movement is being energized with new members. It's one of the things that I love most about warbirds, that it is an inclusive club. And behind the owners and pilots and volunteers is a public that loves these airplanes and attending airshows, even if most of them don't know a Stearman from a Jenny.
When I bought my first warbird the guy told me I'd make 100 new friends. Just add another zero and you'll come close.
