I don’t think losing the one engine (at least in an airbus) is a huge deal, not even hard to deal with. But, all bets are off when it falls off, likely resulting in ruptured hyd lines and fuel cells. Then throw in the alleged loss of the #3 at 500k GW. Screwed…nobody can recover from that.

The tail engine is #2.

I had a 50/50 shot…put it all on black!

Engines are numbered left to right... for those unaware like I was at one point. 
 

Brabus... In the Viper or F-35, that would be "#1".

At the recommendation of Boeing, both UPS AND Purple have grounded their MD-11's.

C-5 and AF 1 both use a version of the CF-6. Of course how they attach to the airframe is where I see this investigation headed. Props and engine mounts keep maintainers/engineers up at night for a reason.

AKA, "the" engine.  Having only one really simplifies which one you're talking about.

Yep, only one engine to worry about vs three or four

Minus the fact the Viper has two different engine manufacturers and different models between manufacturers.

And the Airbus A300/A310, A330, and Boeing 767.

Oh, and in a ton of military marine applications (Spruance, Kidd, Oliver Hazard Perry, Ticonderoga). The CF6 class of engine is all over the place.

Try five engines, with three different ones on the same jet. 
 

Real good friend flew this until RR retired it 2-3 months ago.

I wonder about the throttle spread to get them all making the same power. Otherwise it wouldn't want to fly straight.

Try six, one country has its own.

Once again, Hoover nails it (STS)!
