I wrote articles almost identical to those 25 years ago. IIRC, the L-1011 had a carbon-fiber tailfin, as well. And the other story is the same old, same old for the high-performance composites business. Very little appears to have changed.

A lot of people don't realize how much epoxy is used throughout the structure of an airliner. They probably don't want to know. d8-)

However, they also don't know how much fatigue becomes a problem in all-aluminum aircraft that were designed over the last few decades. DC3's are still flying because the engineers didn't know what a reasonable safety margin was. Now they know, and the life of those planes is finite.

I was told by late father, who was in the aerospace industry in the UK and later US as a stress analyst, maybe 25 years ago that one of the reasons the DC3 kept flying because you could still get fuselages and wings. When the life of the wings was up you bought new ones and the same with the fuselage. I expect like many planes the airframe life is also re-evaluated after actual service conditions have been experienced and extended or otherwise revised.
