The Lockheed Elektra was infamous for its wings mysteriously coming off. Much research finally revealed that dynamic instability (flutter) was the cause. A great deal has been learned about how to prevent this, and a lot of effort goes into designing a wing that isn't susceptible to flutter.
I did the calculations for the 757 elevators to show it wouldn't flutter. And yes, it was also verified on the test stand.
