The R.A.F. Mosquito was a zippy, nimble aircraft, its fuselage built of plywood on a balsa wood core and its wings made of spruce and birch. Other than mechanical working parts, this made the Mosquito nearly all wood.
The Mosquito’s crew of two could take the 18,500 lb. craft to relatively low altitudes to whisk into position, drop its load, and whisk away.
