We have the tendency to lesser the things and start calling serious accidents incidents if there is not casualities. But in the 60s, 70s no aircraft manufacturer had fear of grounding an entire fleet.
Yes, the industry is very safe and fail proof, but are we going to resign safety now? Are we happy with the safety level or we want more.
Strongresolve, As I recall, DC 10s were grounded for a while following the 1979 engine separation at O'Hare. But these are wider issues. Perhaps a new thread would be appropriate to share your more general concerns about aviation safety?
