Over in Jet Blast we have a crowd of PC Simulator pilots who really believe that it is possible for people who are not trained, skilled and professional airline pilots to recover and land a crippled airliner. Its just a fantasy I'm afraid;
I've seen numerous people with no connection to aviation land in sims at their first attempt with nothing more than an instructor talking to them. Then they do it again without the prompting. I mean full flight motion certified CAE sims.
In a real situation the talk down would be available through atc comms, pilot in the tower.
