To grease it on, your sink rate has to be minimum. Or you can 'roll' it on a la 727 so that the mains are going up as the aircraft hits the deck. You risk a very firm landing if you are too late and float if you are too early. Only recommended for the aces.

Another way to arrest sink is with a spurt of power, again not recommended as it increases fwd momentum, speed, fuel, brakes and distance. Or duck below approach angle and level out prior to touch down on 'the spot'. Risk is landing short (unexpected sheer, power loss) and approach obstacle clearance but in both cases, the pax will be impressed.

But it depends on the aircraft, wingloading etc. The 747 will grease it on almost every time because of cushing ground effect as will the 146 because of very forgiving gear geometry.
