Some planes seem to have a tendency to take specific damage.  Is it only my imagination or if not, is this based in reality?  Not whining, just curious.
For instance:
C-202       seems to get the engine block seized in a single burst
109 E-4    wing cannon damage
P-40E       frequent flap damage
F6F          oil hits
Ki-84        pilot wounds
Mossy       pilot wounds
P-47         main fuel hits/fires
Why don't certain aircraft catch fire?  Spits wings break off like stale crackers but never a spark (except one I downed with a SpitI).  
Lancs don't seem to catch fire, even when wings get blown off.  And did B-24s really light up that easily or is it just in game?  
Also, the wirble seems more resistant to bomb splash damage than the Panzer.
