Greater production and use of the Mosquito is a good point. We should remember, though, that Messrs de Havilland’s original intention was to use “not war essential” cabinet making capacity and “not war essential” wood to make a useful contribution to the war effort. From the skilled workforce available, there was a limit to production capacity. Additionally, much of the wood needed started life across the Atlantic. This had to be transported by sea as sheets or finished sub assemblies, thus competing with other essential material in limited convoy capacity.
Perhaps more useful would have been the abandonment of Stirling and Wellington production much sooner and turning the capacity over to Lancasters.
