Most of the structure is Aluminium with very little steel if any, the He111 has a steel wing spar but would take some serious grinding to get anywhere near it.
Typically using steel nuts and bolts is no good as it reacts with the alloy, and adds to the weight of the aircraft dramatically.
Please no sparks and Hollywood style fires and effects, the IL2 series has already suffered exploding planes and Hollywood effects, most belly landings were uneventful affairs.
Besides SoW will be mostly grass airfields and any pilot going for a belly landing will take the grass over the concrete probably.
Wing of P51 replica.
