Ok, I accept that... had a bit of doubt, but it makes sense now. Scraping the wing on the concrete does not weaken or damage the wing in any way as long as the damage text list shows no damage.
I'll take that as the truth from HTC. Hopefully others that read or posted here learned something as well. Thank you.
I don't think scraping the wing causes... damage over all - for example I bounce quite hard when I land, I never had landing gears shed off.... Now if you take off and forget to raise your landing gears they will shed off after you get some speed.
I do know if you bump a building doing 5mph it will shred a wing right off even if you barely touch the wingtip, few times I've taken off I've scrapped a few wings, hell I even had one spin me 90 degrees around.
Its a bit surprisingly that we don't have it modeled for damage, if you scrap a wingtip wouldn't it come off? or seriously damage the wing? I wouldn't think so since there are no major... systems int he wing tips, maybe a Spitfire with the outboard .303, but I dont
think it would be damaged by scraping wings.
