One example is the Glasflugel Libelle first-generation composite sailplane
first sold in the mid 1960's. Most of them are still flying and in
beautiful condition to boot. They sell on the used market for 10,000 to
15,000 Dollars.



Yep, I own H301 Libelle #19. She's 42 this year. Flew 5 or 6 flights of
200 miles long or more this past spring. About 2500 hours flying time.
I've put about 300 on her in the 5 years I've owned her. Flown through
some hellacious turbulence and some pretty hard cowpasture landings.
She's still smooth and shiny although some small areas of finish are
starting to turn a bit yellow. No structural problems. No AD's on the
composite structure.

The more modern composite birds like the Diamond DA-20 hold up pretty
well even sitting out in the weather for years.
