I suspect the more serious ramifications of this will be to add weight to the 'elf 'n safety police who have already stopped such aircraft carrying paying pax in the UK.
Seriously? Why? The aircraft carried untold zillions of people in decades past, safely. Why would it be suddenly unsafe now?
Out of the five DC-3s that I used to fly in as a pax way back then as a kid, two or three, and probably more, have ended up fatal. Yet, I would like fly in them if an opportunity arose.
Ironically, if a large number of airframes end up destroyed in crashes, that may simply be an indication of reliability. After all, if you keep an aircraft airworthy with proper maintenance, you can fly it indefinitely … and if you fly it indefinitely, then logically the only thing that will stop it from flying is a crash that results in a write-off. So you might actually expect to see all of the most reliable aircraft end their lives in massive crashes.
