Ajay, you're beating a bad drum and it sounds awful.
Jet transports have a good glide ratio but it is with a clean wing and speed is relatively high, like maybe 200-250 knots depending on weight. When it is time to land much energy has to be dissipated at just the right spot relative to the touch down point. This is done by extending gear and flaps - if there is hydraulic power to do it - and as speed bleeds off, drag goes up quick and without engine power, the only way to control sink is to keep increasing the angle of attack until the touch down. There is no such thing as an on speed stable approach at normal landing speeds (120-140) without engine power.
What Capt. Sullenberger decided was the best and safest thing to do under the circumstances.
He set up a glide down the river and when at a flare height, leveled off to dissipate speed and landed in the water as slow as possible. It was a classic water landing, perfectly executed, and not a soul was lost.
It is not the same as losing an engine in your RV, Ajay.
