Loss of an engine. . .big deal. . .that is why they have two.
Around 20 years ago, a plane had an engine fall apart like that...and it damaged hydraulic lines that caused the pilot to lose control. One good reason to land.
I’ve been in an airplane that had an engine catch fire, and they landed it right away in some remote airport - took around 8 hours to get bused back to Atlanta and try again.
