ZFT...
I consider a DC8 a modern airliner...A Japan Air Lines DC8 flying into KSFO with gear down fully configured for landing ended up in the bay...stable approach right into the bay. everyone was ok...no one hurt. And it was at night!
Plane was pulled out, dried out fixed up and flew another 20 years or more. I encourage you to look it up.
I want to add one other thing to this threaed...on final if you are clean and at 250 knots or so, you might be able to glide to the runway if you don't change configuration...or wait till landing is assured if you have lost all engines.
we were req'd to spool up the engines at 3000' agl /afe to make sure they responded...and if they didn't, you might make the field clean at speed.
