Wings keep you in the air, not the engines. If you have enough altitude to convert into forward speed, and that speed takes you far enough to a suitable landing surface, you have a chance of survival.
On the other hand, in jets that need lots of speed to produce lift, eg. MiG-21 or F-104, the distance that you have available without the engine (glide ratio) is so low that recommanded thing to do is just make sure the aircraft doesn't hit anyone on the ground and eject.
