It's pretty clear that as the aircraft became more advanced, bigger and more complicated, keeping the later airplanes flying in civilian hands has proven a real challenge and the B-29 seems to be right at the breaking point. The point being, it and most of the advanced bombers, transports, fighters and airliners that came after this period are likely to be relegated to static displays only.
This gets me to thinking on how to best utilize the artifacts that we do have left. People pay a fair amount to get a ride in an WWII war bird, but it's clear that it's not enough and it won't go on forever. What if we took a few of the remaining airframes and built full motion simulators with them. Imagine not only going for a ride in a B-17, but on a combat mission over Europe! Everything as realistic as possible, except the dead and dying part.
Get the best of the war bird restoration community together with the simulator companies and the folks from Disneyland and you could make a real attraction that could entertain and educate. Maybe even fighter experiences from the other side as well.
Just a thought. Without some seriously wealthy people taking an interest, one by one, all the old birds will either be grounded or crashed. Eventually, this and maybe the next generation will effectively "use up" all the WWII war birds and they will slip into the purgatory of the museum and history books. Perhaps the simulator idea will help keep the sights, sounds and stories of these birds and the birds after WWII alive for generations to come.
