Airplane specific weight (hohohoho!..)
I was wondering if any math fan has ever calculated the "specific weight" of an airplane, I mean the total volume versus the weight...
not too difficult to calculate, but certainly to me, yes...
What could that be compared to? light wood?
In case my question is clear as mud: what material could we use to build a 1:1 scale aircraft model in one solid piece resulting in a realistic total weight?
