S**t happens from time to time. Fortunately, with time things have become far more reliable.
Back in 65 I had two engines quit on me on two successive days for completely different reasons. Both landings uneventful. As time went by I haven't had what you would strictly call engine failures but power loss as the engines did not fail from internal causes. One on a 727 from FOD and one on each 320 & 340 due to large birds. All uneventful.
Hilico - does a tail rotor failure count??? - now that was interesting. Nearly lost it but fortunately all turned out ok in the end.
Have a nice day
