It is, the WWII Mosquito Fighter-Bomber was made from high grade ply and it flew faster than contemporary aluminium fighters, was incredibly durable (except for some de-lamination problems in hot humid far-east environs) and was actually stunningly beautiful.

Also mostly plywood: the Spruce Goose https://en.wikipedia.org/wiki/Hughes_H-4_Hercules

which is simply massive: 320 ft wingspan, the largest of any flown aircraft.

Haha, that was the first aircraft I thought of too!

The earlier de Havilland Comet was also incredibly beautiful and made by innovative woodworking techniques: https://en.wikipedia.org/wiki/De_Havilland_DH.88_Comet?oldfo..., one of my favorite planes ever.

I too was surprised to find out just how much variety and quality of plywood there is. I always thought it was a relatively cheap, kind of crappy alternative to good lumber. But since I've started following hobby laser cutting, I've been finding out that good plywood really makes a difference if you want good results.

I've had really good experiences with birch based plywood of the better grades and for heavier applications a grade that is used in construction to make the forms for concrete casting.

Where in Ontario? This would be interesting to see for myself.

Thessalon iirc on Hwy 17.
