Cables should be damageable, but IL2:FB makes them too fragile or without redundancies. Something seems off in Il-2 given how frequently and fatally they get hit.
A story picking up halfway through a mission in a Mosquito B.Mk IV:
'Suddenly, there were flashes and black puffs of flak. I remember thinking "this is not what you get in a Mosquito - you're too fast for this sort of thing" - and then just before I dropped my bombs there was a violent bumb. I thought it outrageous that one could be downed at night in a Mosquito. It was just not done. It was unsporting and not in good form at all.
'Anyway, we turned round and weaved our way back across northern Germany and over the Dutch coast in the direction of home - we were bathed in brilliant moonlight throughout the operation. We had one loss - Wg Cdr Peter Shand, OC No 139 Sqn (and his navigator, Plt Off C D Handley DFM), who we subsequently heard had been downed (by Oberluetnant Lothar Linke of IV.NJG 1) on the way home.
'Once back on the ground, we were debriefed and went to bed. When I went up to the flights the next morning I was asked if I realized that I had been hit the night before? I said, "No. I had a bump and realized that there had been a burst fairly close. I didn't know I had been hit. I suppose there are a few tiny holes in the wing or something?" They said, "Oh no. You've virtually had it". A piece of shrapnel had gone right through the tail of the Mosquito where the elevator wires all link up with the tailplane and rudder. All but one of these wires had been totally severed, the sole intact strand on a single control line allowing me to fly the Mosquito as if nothing had happened. I was unaware that anything was wrong at all as the aircraft had handled perfectly.
