…but they may be on the bottom rung of the future.
and lets face it if rockets were made of real wood tey wouldn't be very good!
1) Maybe they're the bottom rung of the present
2) Rockets are supposed to sound good!
Sorry, Clansfolk — What's go good about wood is that it has warmth, vibrance and visual beauty that will probably never be reproduced by plastic, IMO. Ovation has been churning out its Thalidamide helicopters for years and I've never heard one of them that's improved with age.
As for giving other materials a chance — I've got a nickel-plated brass National that I love... Go figure, huh?
