What a load of BS. Have either of you guys ever seen or flown a high
performance sailplane? Where *only* airframe performance counts -
aircraft
use composite construction. Anybody heard of Rutan?


Composites, sure. But fiberglass specifically, well.....

Rutan's designs, such as the round-the-world Voyager, or Adam Aircraft's
A500... were done in carbon fiber and kevlar.... was there very much
fiberglass involved?

As for the obsolescence of aluminum, especially in alloy, try the
