... unless the aircraft has flown out of range of the previously set ATC.  It's certainly worth a try, but I would think having 121.5 in your mind as the next step would be essential.

I couldn't agree more.

Yes of course, if it is impossible to raise anybody on the air-to-ground frequency what was previously used. But then, chances are it will be a pilot, who was monitoring the frequency, that will respond. This pilot will have no idea where you are. It is not like 121.5 was really monitored by ATC. But yes, it would be your go to frequency if you have no other frequency to work with (no response on the previously used frequency).

And the odds of failure are even higher if nobody on board does anything.

I think this says it all.  If something happens that incapacitates all pilots (the assigned crew, any dead-heading, off duty, retired, vacationing), all partially trained cabin crew, and all non-commercial pilots on board there is still a chance (assuming that the anti-hijacking features have been disabled before the pilots were) that one of the passengers could get the information together and get the plane on the ground.  Maybe a landing.  Maybe a survivable crash.  Not a great chance, but somewhat better than everyone assuming the tuck position and waiting for whatever happens.

Emergency frequency is 121.5MHz

Other than that, I know very little.

I think you are the one to which I suggested a movie once. This time my suggestion is "Mercy Mission, the rescue of flight 771". It is the true story of a guy who get lost over the Pacific. An airline pilot tries to locate him. It is a movie, so the story is not 100% accurate. But in the book "Emergency" by Stanley Stewart, you can find exactly what happened.

Flight attendant Andreas Prodromou, from Helios Flight 522 wished he would have known how to fly the 737.

But I never heard about flight attendants being trained to fly an aircraft in an emergency.
