A hypothetical situation, and a doubt

This won't happen, yet...

On takeoff, one of your engines sucks in a bird or simply fails, and
you're left with just one turbine. You declare emergency, etc. but in
returning for a landing, there occurs a situation during finals - you
somehow botch up the approach or some unexpected weather is encountered
- which in normal circumstances would've warranted a go-around. Since
you can't do that now with one engine, how would you salvage the
situation?

No "I'm good enough never to screw up approaches" for an answer, thanks

Turbine powered airplanes can make single-engine missed
approaches, some piston engined twins can also. Gross
weights above 6,000 pounds require positive climb on one
engine. But even if you can't do a missed approach, you're
no worse off than you'd be in a single in the same place.

One of the things I was taught during my instrument training was not to
takeoff into conditions which were not good enough to make an immediate
return should just such a instance occur.

Maybe that is what happened he http://www.cnn.com/2006/US/04/03/c5.crash/

- which in normal circumstances would've warranted a go-around. Since

Of course you can go-around on one engine. Transport category a/c
are required by regulation to be able to do that.
After all....the airplane is able to continue the takeoff after
an engine failure while still on the runway and past the V1 speed,
it stands to reason that if already airborne and at a speed higher
than V1, it can continue flying.

Correct - Since the OP said "turbine" and "ingestion" we can assume we
are referring to a transport category aircraft, which is indeed capable
of doing the go-aound on one engine (or two, or three - depends on what
an engine-out condition indicates for a given type).

Nevertheless, such situations have given rise to many incidents and some
accidents. Examples : What seemed to be an engine-out condition, due to a
bird strike, turned out to be a both-engines-out condition (due to bird
strike) and the plane did not complete the go-around procedure. OR : In
haste and confusion, flight crew raised gear but not flaps, and the plane
was not able to initiate go around, settled to runway with too little
runway remaining, but was able to stop in available runway due to gear-up
landing - OR : Go-around was initiated, but fuel selection was
inappropriate and plane made forced landing, believing they had a total
power loss.....

In a smaller plane (light twin) the available power is not adequate to
perform a go-around on one engine with adequate safety margins, and you
must get it down, even if you break it. In a transport plane with two
engines, it is perfectly possible, but you must weigh the risk to benefit
ratio, and maximize crew resource management to make sure everything is
done by the book. In a 747 you should hardly notice any performance loss.

I believe he (C5) lost 3 of 4, not just 1 of 2.
Of course I have lost 1 of 4, and even 2 of 8, and returned safely. Granted,
we could not dump fuel with the 8 engine bird, and had to fly about 5 hours
to burn down to landing weight.

I get it now.
And nicely put, buddy, as usual
I thought you were still snowed under with computer work, thus Option 2

Hmmm... lost two of eight huh? Eight engines, you a Buff driver?
Cool...

I know it isn't what you're saying but if you lose one engine in a
4-engine craft, you don't return but carry on, surely?!
