how on earth do you fix that?
Well, you either have different (skilled) pilots like Steve Hinton or Rick Volker
fly the aircraft (not bloodly likely) or ...
You train up the warbird pilots. See, the problem is that they can't get enough
stick time on the antique stuff, to get any good at it, especially when the organization
splits up the very few hours available on type, to a pool of pilots, none of whom
get enough hours.
So, they're going to have to get stick time on other stuff, and you hope it transfers.
Rick wrote an article about this, a while back.
The problem is, most people want to be a rock star, not a session musician.
There is no glory (or flight suits) for session musicians.
Note that there are schools to teach pilots to fly different types. We call it
"test pilot school" and it costs millions of dollars per student, and takes at
least a year. Creates good session musicians.
In the 21st century, no one wants to spend even one year, getting good at
anything, even if it's the difference between life and death to them. I find
that odd, that they value their lives so cheaply, but I am a 20th century pilot
with half a century in aviation so far so I probably have the wrong idea about it.
