Hi Da Judge:

Got a little experience in flying classic/warbirds and I am not sure this is the answer you are looking for.
I have flown many types such as the Tiger Moth, Chipmunk, Harvard, Auster, Otter, T-33, Dak (C47), Canso (Catalina, PBY) and all are classics and could be considered warbirds as well.
I am well past a half century by close to several decades and like many of my peers it takes a long time to learn something.
I am one of those who always thought the grass looked greener on the other side but as year pass you by you learn different. :)
It is the same with aircraft, yes the old "Otter and T-33" were the cat's ass at one time but as time goes on you find they are only stepping stones.
You jump into a nice little Cessna 150 and it will fly the same as anything else. You push the wheel forward, the buildings get bigger, pull it back and the buildings get smaller. All aircraft pretty much fly the same way in that respect.
Oh the little Cessna 150 won't go quite as fast as some of those other types, won't have nearly as many guages and switches, won't burn as much fuel either, won't go quite as far on fuel or carry as many folks.
But, as you cruise merrily on your way from point "A" to "B" defying the elements and look out onto the horizon it won't look any different than if you were in any other aeroplane. ;)
When you land and walk into the airport you will be given the same respect, treated equally as any other pilot whether he walks in with four stripes on his shoulders or not.
An aircraft is a tool, to be used for commerce or pleasure, some cost more to operate than others. There is nothing wrong with wanting to fly any aircraft, classic/warbird, set your goals and hold on to your dream and as experience and time pass you by you will probably agree, yes they all do fly the same. ;)
There is my long winded answer Da Judge. :)
Cheers...Happy Landings...Doug
