Looks like a super picture coming up. I would suggest leaving the nose of the grounded Whirlwind the same as the airbourne one.
I never went to NG but I would think it would be unlikely to be concrete or tarmac; more like crushed gravel or stone.
Looking at websites of NG at the time it looked like scraped pads.
