According to my friend who used to work with that stuff, the bigger “problem” is mostly with regulations and balancing the risks; the damage potential of an aircraft accident (loss of life, brand reputation, recalls, etc) is exponentially more expensive than however much you’d save in production costs. Closed-loop recycling is usually the focus instead. But it would of course be cool.
At least that’s kinda Airbuses viewpoint on it. Boeing on the other hand might be fine with delivering dodgy stuff and bribing away any possible fines ;)




I used to use that kind of thing, and it was nice until I needed to carry a lever tumbler lock key and some other keys that were abnormally shaped.
