One plane worth mentioning because of its versatility was the British Mosquito, it was a good fighter, an excellent ground and ship attack plane and a light bomberBecause the Mosquito was made primarily of wood, it was a lousy radar reflector as well, with radar being more primitive than what we now know.
Yep, a plywood plane when everyone thought that metal was the only way to go. Plywood was cheap and available so that was what was used, and be weight factor figured in. Germany tried to build their own mosquito, calling it the Moskito I believe, but their glue factory was bombed and that dried up their supply of plywood, the substitute glue they tried to use actually ate up the wood.
The mosquito was a great success and was used by several nations for years after WWII ended.
