"[...] plastics had significantly accelerated due to the military’s need during WWII for lighter, more durable materials to create 3D topographical maps"
What?! Citation needed. Lots of topomaps were printed on paper, but I've never heard of the military using 3d plastic maps. Certainly not enough to accelerate the development of plastics. Nor can I find any credible source for the claim.
