If you accept the odds of that I have a Kansas City Sea front condo to sell you...
A 777 when both engines are flamed out will fly a phugoid descent - this was ascertained by someone with time on a commercial 777 simulator. So it does not exceed VMO as it pitches up as speed increases then down when it reduces.
It does not seem likely the both engines would flame out at the same time. At the end there would be a period of asymetric thrust and probably a spiral dive into the ocean.
