Durability of aircraft to MG (< 8mm) guns

[Flying Pencil]

I wonder about durability of aircraft to MG damage.
Will the game challenge fighters players to marksmanship and get in point blank?

In IL-2 and especially many other games, a quick burst and the EA is a flaming ball of fire (speaking of Rifle Caliber Munitions, not .50 and heavier)
Reality is, aircraft on both sides RTB with hundreds of holes. It was said half jokingly "Its not the damage you do, but how much lead you fill the EA with"

Simply a case of armaments not keeping up with times. The guns where practically the same used in WW1. Sure some 20mm was showing up, but in 1940 it was by far 7.62mm and 7.92mm rounds.

RAF pilots reported emptying their entire load into He-111, only to see it fly away (chances are the 111 was to never fly again, and no, the Hurri pilot did not miss)

For example, behind the pilot is a large bulkhead, while not armored, would have stopped most Rifle Caliber Munitions from getting to him, and resulted in He-111's suffering fewer losses then Ju-88's in BoB

In another game I play, rarely is the He-111 pilot killed, usually due to frontal attacks.
