Certainly, for a more authoritative discussion on "manual reversion" on a 737 see here (https://aviation.stackexchange.com/questions/77693/are-737-pilots-required-to-train-in-manual-reversion-flight https://aviation.stackexchange.com/questions/77693/are-737-p...), your favorite search engine can also provide a decent body of technical and anecdotal data. As far as survivability of suddenly losing all engines at low altitude, I relied on my own knowledge and experience, however I can refer you to Wikipedia (https://en.wikipedia.org/wiki/List_of_airline_flights_that_required_gliding https://en.wikipedia.org/wiki/List_of_airline_flights_that_r...). Specifically https://en.wikipedia.org/wiki/American_Airlines_Flight_1572 https://en.wikipedia.org/wiki/American_Airlines_Flight_1572 and https://en.wikipedia.org/wiki/US_Airways_Flight_1549 https://en.wikipedia.org/wiki/US_Airways_Flight_1549. Those 2 are just about (IMO) the complete body of cases where there was something to learn from the aircrews actions following the loss of power. That being said, there actions were very specific to their circumstances, would be very difficult to train for, and the pilots survived to provide first hand accounts instead of relying on the CVR.
