Probably add Guruda 421 to that list. IMO an equal or greater save than Sully.
Agree. Good description here: https://en.wikipedia.org/wiki/Garuda...sia_Flight_421
Please excuse slight thread drift, but talking about forced landings, here In brief is the description of what happened to Garuda Flight 421. At least Sully was VMC the whole time which helped him see where he was landing (ditching).

: While descending IMC, the Garuda 737 penetrates a supercell thunderstorm with tops 75,000. Radar later found to be poorly maintained giving spurious or no returns. . Blinding rain causes flameout both engines around 19,000 feet. Unbeknown to crew, the aircraft battery has been badly maintained causing complete electrical failure the moment the crew try to start the APU - in IMC the whole time - the total electrical failure causes failure of standby artificial horizon - miraculously the 737 exits cloud just as the standby AH gives up the ghost - again good fortune smiles as they spot a winding river in the jungle below. With no engines means no hydraulics and that means no flaps. Successfully ditches at 185 knots flapless with the only casualty a flight attendant who unfortunately is caught at the back of the aircraft and drowns.

If ever this sort of scenario was ever tried in a simulator the crew would be entitled to say "Rubbish! it would never happen." Yet thunderstorm penetrations happen all over the world every day but fortunately not with that combination of circumstances.

Yet handling a dead stick landing from high altitude is not a mandatory sequence during simulator training while millions of dollars are wasted on UPRT in simulators, including the time and cost of modifying software for an exercise which can be adequately trained in 45 minutes by a competent instructor.
Rant over..
