I've been flying mostly during the earlier years with Esc Laf, and I personally can't understand how EIIIs could have survived very long.
Sure, I've been jumped when I get a bad case of target fixation... Normally though, any EIIIs I see in the air are Earth bound quickly.
For you guys out there that enjoy the bebe, targeting isn't all that hard - just use the "cap" on the engine cowl and the cross of the wires
as aiming points. Ideally you want to close to less than 50' giver or take, and fire at just below the wires. If you are into long range shooting,
which is much harder with the tracer mod, firing at a point just above the "cap" usually lands solid at around 250' if I remember correctly...
