I really do think it is amusing. Here are my break-downs of what your average pilot thinks about the "plane-pilot" equation, along with my personal perspective on why I think that.
Newb pilot - All plane. Reason being said newb ups, gets his bellybutton handed to em 4 or 5 times, then switches to whatever plane has been handing him his ass, expecting it to make a difference.
Borderline Newb - Has realized that pilot plays some role in the equation, because the same guys always seem to hand him his bellybutton even if they are in the same plane. So probably 50-50 pilot plane.
Average pilot - Can kill baby seals in whatever plane he wants to, therefore leading him to think that the pilot is more important than the plane. Call it 75-25.
Good pilot - Can usually kill average pilots in whatever plane, usually loses to "great" pilots in whatever plane. Call it about 90-10.
"Great" pilot - Has found a plane that he is very comfortable flying, can usually kill anyone, unless they run into co-skilled pilot in ... a better plane. Call it back to about 50-50.
Honest pilot.. (me) call it 10-90 plane/pilot. Now matter how "great" you are, you can't make a plane do something it can't do.
Most of the self-proclaimed "great" pilots fly extraordinarily fast planes (1945, as a general rule), and tend to run at the first sign of trouble.
Karnak, you've got it right in my opinion. Anyone who can't see what a complete and total performance advantage the La-7 gives even the most pathetic newb of a seal pup target is blind, or deluded.
By the way Humble... if I took you up on your offer.. I'd take the La-7 and kill you in anything if I had a 5k alt advantage to start.
It is the plane, not the pilot.
