Please excuse, slightly off topic but regarding the relevance of wood as a suitable aviation construction material. It was certainly up to the manufacture of the 'Timber Terror' or 'Wooden Wonder' Mosquito twin engine bomber of WW11.
Mosquito's were made of custom plywood. The fuselage, a frameless monocoque shell made of ⅜ in (9.5 mm) sheets of Ecuadorean balsawood sandwiched between sheets of Canadian birch. In areas needing extra strength—such as along cut-outs—stronger woods replaced the balsa filler. Plys were formed to shape by band clamps over large concrete moulds, each holding one half of the fuselage, split vertically. As Casein-based glue in the plywood dried, carpenters cut a sawtooth joint into their edges while other workers installed the controls and cabling on the inside wall. When the glue was completely dried, the two halves were glued and screwed together. A covering of doped Madapolam (a fine plain woven cotton) fabric completed the unit.
Wings were similar construction but used different materials and techniques. The main wing was built as a single unit. To form the basic shape, two birch plywood box spars were connected by plywood ribs, and stringers spanned the ribs. The skinning was also birch plywood, one layer thick on the bottom and doubled up on the top; between the two top layers was another layer of fir stringers. Brass screws, 30,000 per wing were used. The wing was completed with wooden flaps and aluminium ailerons.
With both fuselage parts complete it was lowered onto the wing, and once again glued and screwed together. The remainder consisted of wooden horizontal and vertical tail surfaces, with aluminium control surfaces. Engine mounts of welded steel tube were added, along with simple landing gear oleos filled with rubber blocks. Wood was used to carry only in-plane loads, with metal fittings used for all triaxially loaded components such as landing gear, engine mounts, control surface mounting brackets, and the wing-to-fuselage junction. Total weight of metal castings and forgings used was only 280 lb (130 kg).
Glue initially used was casein-based. After some unexplained crashes of aircraft operating in tropical climates, this was changed to "Aerolite", a synthetic urea-formaldehyde adhesive developed by Dr. Norman de Bruyne, better able to resist deterioration in high humidity conditions. De Havilland also pioneered the use of radio frequency (RF) heating to accelerate curing of the adhesive.
In England, fuselage shells were mainly made by furniture companies, Ronson, E. Gomme, Parker Knoll and Styles & Mealing. The specialized wood veneer used in the construction of the Mosquito was made by Roddis Manufacturing in Marshfield, Wisconsin, United States. Hamilton Roddis had teams of women ironing the (unusually thin) strong wood veneer product before shipping to the UK. Wing spars were made by J.B. Heath and Dancer & Hearne. Many other parts, including flaps, flap shrouds, fins, leading edge assemblies and bomb doors were produced in High Wycombe, Buckinghamshire, well suited to these tasks due to a well established furniture-manufacturing industry. Dancer & Hearne processed much of the wood from start to finish, receiving timber and transforming it into finished wing spars at their High Wycombe factory.
About 5,000 of 7,781 Mosquitos made contained parts made in High Wycombe. In Canada, fuselages were built in the Oshawa, Ontario plant of General Motors of Canada Limited and shipped to De Havilland of Canada in Toronto for mating to fuselages and completion. De Havilland Australia started construction in Sydney. These production lines added 1,134 from Canada and 212 from Australia. It could carry 1,000 lb (454 kg) of bombs for 1,500 mi (2,414 km) at a speed of almost 400 mph (644 km/h), almost twice that of contemporary bombers, and the prototype in testing exceeding the speed of the current Spitfire of the time.
