Commercial jet engine in-flight failure rate

How often does an engine fail? Once. I was actually thinking of a statistical number. If you go look up General Electric aircraft engines, they will tell you that it has like a 99.6 percent probability per hour of not failing. Well, that means you're going to get a failure about every 250 to 300 hours. How many people have flown 250 hours? Yeah, okay — I've probably flown several thousand hours. They don't usually tell you when they have to shut down one of the engines, but they do, in flight.
