Or a bird strike/ingestion.

I second that.

An interesting fact:

A four engine jet is twice as likely to experience an engine failure as a two engine jet. It is just pure mathematical logic and also one of the bases for the introduction of ETOPS (Extended-range Twin-engine Operations Performance Standards). This allows modern twin engine jets to fly further than 60 minutes from a suitable landing field, generally over water. Certain procedures and restrictions apply.

Compressor stalls happen.

Nope. Climate change.
