...a dumb question on fighter plane canopies. what were those two-piece bubble canopies on the P-51D and later versions of the Spitfire made of? glass or plastic?
so they already had plastics then. thanks. from the wiki site: During World War II both Allied and Axis forces used acrylic glass for submarine periscopes and aircraft windshields, canopies, and gun turrets. Airplane pilots whose eyes were damaged by flying shards of PMMA fared much better than those injured by standard glass, demonstrating the much-increased compatibility between human tissue and PMMA as compared to glass.[
It has been nicely answered by Nolan00 but the airbase I grew up near, Craig Air Force Base, near Selma , Al, had lots of WW2 planes just after the war and they always used "perspec" as a common name , it is listed in the WIKI link and I imagine a particular manufacturer name.
