Way back, I believe the first jet passenger jet was the Lockheed

search for a cause was instituted. In the end, again if I remember
correctly, the conclusion was that the wing spar failed from fatigue
because the wing was nutating, a slight circular motion due to
gyroscopic effects.

To jog your memory:

Maybe that's the same thing caused the FL seaplane crash.

The Electra problem happened pretty soon after they came out. Those
seaplanes have been around a long time.
