You realize they are building all new FW-190's, Me-262's, F3F's, Yak 3's and more from plans, right?
Yeah, it's sad to lose one but I'd much rather see them flying than gathering dust in a museum.
Didn't lose the pilots. There's the bright side.
Probably the toughest thing is going to be engines. A lot of substitution going on in that area already due to scarcity.
Of course, if the desire and the money is there, there would eventually be new Packard Merlins.
