Leftover screws and bolts are bad! /ubbthreads/images/graemlins/insane.gif
This week in A&P school we overhauled a piston engine. When one group was done, they had several crankcase through bolts left over and had to take it back apart. /ubbthreads/images/graemlins/shocked.gif

That could fit with the joke, "Ladies and gentlemen this is your captain speaking, if you loo OH MY GOD!!!!!!!" over in the aviation humor forum.
Good god, how did that engine stay running if it did. I'm sure some of those parts cant take 600 mph wind, but mabey they can, I dont know. I bet there was a hell of a lot of noise and drag when that happend.

Look carefully, none of the engine is sticking out of the faring (or what's left of it). They are inside the "bubble" of the slipstream. That top peice of the pylon faring that is sticking out in the wind dosen't have much time left though.
The first thing I would have done is to slow way down. Then probably take that engine off line (just in case something had been broken when the cowling let go), and make a normal single engine landing at the nearst suitable airport.
I've always said if the flight controls, at least one engine is working, and if you're not on fire, then it's not a real emergency. That wouldn't stop me from saying the magic words to let ATC know what is going on, but I wouldn't be too worried. Just keep the airplane stable and land as soon as practical. I hear way too many reports of pilots crashing because their door opened, or some other malfunction that didn't affect the planes ability to fly. /ubbthreads/images/graemlins/banghead.gif
Look at some pictures of WW2 bombers that have returned shot completely to hell. Some B-17s made it back to England with huge holes in them. As long as the airplane will fly, then fly the airplane.

It doesn't look like it's doing too bad there! What is the big squarish heatsink looking thing on the side?
Is the cowling the outer alloy "shell" of the engine? I don't understand how that could detach!
*examines photo again*
Ouch my eyes just crossed!

Probably a loose series of rivets...You get airflow under the cowling at that kind of speed, and bad things happen. /ubbthreads/images/graemlins/smile.gif
EDIT: Scratch what I said about rivets. Latches, duh. /ubbthreads/images/graemlins/grin.gif
Oh, and I'll betcha that heatsink-looking-thing is the FADEC. Dunno though!

"Ah, ladies and gentlemen from the flight deck. Ah, we've got a minor malfunction on the left engine, but we'll be just fine. We know you were hoping to make it over to France today, but we'll be diverting to Heathrow just in case.
From all of us here at Ryanair, thanks for flying with us, and we'll get you on your way to France just as soon as we put a little cover on the engine."
Off mike -- "I'm gonna bleeping kill that bleeping mechanic."

Different RyanAir - if it was the European Ryanair I would guess it took off in that condition

I belive that section is just latched together and opens into two halves. You can see the on whats left of it. I suppose it didn't get latched right and it opened in flight. But I'm no airplane mechanic so I dont know for sure.

The engine acess cowlings are hinged at the top (you can see the hinges in the photo) and are held together at the bottom with simple latches. They are called clamshells and open up like their namesake. The FO should have checked the latches on preflight, my guess is he didn't. The likelyhood of several latches all failng at the same time is too remote to seriously consider.
Another possibility is that a stress crack developed along a line of rivets and slowly grew untill it failed.
The cowling isn't a structural part of a jet engine, it just covers thing up for drag. They are useually made of light materials and composites. Ocasionaly you'll see a car running around without it's hood, same thing on a jet.
Ironicaly on a piston engine the cowling and baffels are critical for cooling the cylinders, especially the rear ones. Never run up an piston engine without a cowling for more than a few seconds. On older airplanes that didn't have full cowlings still had cooling scoops, example a J-3 cub.
