A whopping 20%? lol

I would suspect that while some of it may be for structural integrity, 80% of a plane being CF is pretty impressive and perhaps it should tell us that CF, science/tech has come a long way. ****, maybe the 20% is simply there to appease insurance folk? Bit of a stretch, but 80% instills a lot of confidence in the final product being mostly made up of carbon fiber.

Most plane accidents happen to pilot error these days and those that didn't happen to pilot error, happened with a plane being composed of METAL. So it's really a moot point to argue otherwise.

I mean hell, look at Tesla, making huge inroads (pun intended) into electric vehicles.
Yet there are still those that crap on it about range. If one is not comfortable with the tech, don't buy it. If you're going on a long trip and can't plan it with all the charging stations around, which btw, the Tesla charging stations are so scattered in a way that a person can indeed make it across the U.S. without failing to get to a station to charge up, however, perhaps maybe that class of vehicle is not for those who aren't very intelligent and/or intuitive? aka, "Pilot error?"
