The 12 has a composite Glass - Balsa - Glass Fuselage
that is probably at least 0.75 inches thick. It is
a very, very sturdy structure.

The 12 would probably be airworthy with either the
glass alone or the wood alone. Laminated together,
it is a tank.

The designer of the ASW 12 also designed the ASW 24, for which he was
awarded an OSTIV prize for his contribution to safety. I'm tempted to
believe he learned a lot between the 12 and the 24. Some features, like
the very stiff cockpit rails, glass, Kevlar, and carbon construction,
and a "soft" nose, are not present in the 12.

It would be interesting to hear his opinion (and those of other
knowledgeable people) on the relative merits of the two fuselage
constructions.
