Aren't Boeing 747s the only 4 engine commercial planes? What if the plane only has two engines? Or does it not work that way?

And, usually, commercial airliners have four engines. They can land with either three, or even two engines still running. If you get all the way down to one, you're pretty well screwed. By that time, the amount of thrust from the engine is no longer able keep the plane at the speed necessary to achieve lift.
With one engine on a modern 4 engine passenger plane, you might still be able to fly (just) or at least lose height more slowly.
Even without any working engines, you can glide. You can`t get a net lift, but you can get a controlled descent. You`re not screwed if there`s an airport close enough. A modern large passenger plane at a normal cruising altitude could be glided about 100 miles and then landed, if the pilot is good and conditions aren`t too bad.

The last thing I want to see flying? Heck, I'd be pressed against the window wanting to get a better look.
