Interesting.
It’s easy to get wrapped up in the glamour of flying aeroplanes, but the supplies used to make and operate them is often overlooked. Few seem to give thought of the petroleum and oil needed for operations, the rubber needed for tyres, or indeed the food needed for The crews and maintainers.

The use of aircraft-grade wood is mentioned but not the use of regular wood used for the unglamorous but essential task of shipping supplies.

I recently read a book on the famous Dodge 3/4 ton military trucks used by the U.S. and allies supplied under lend lease.
In the days before roll on – roll off ships, the trucks were disassembled and crated for shipping to better utilize space in ships. That one truck plant alone needed 175,000 board feet or lumber a day. That’s I’m addition to the wood needed for truck production.

I’m certain that the extensive Canadian forests provided much of that materir.
