Very impressive how slow he got the plane to go. Without using the engines for reverse thrust, I don't know how one would slow down.

- vijayshankar 18y agoI think they don't use engines to slow down. I have seen some parts of the wings (like the rear half of the wings..) along its length standing up right ( something like right angle to the direction of motion of plane) putting a lot of resistance to the air while planes need to slow down. Using the engine to slow down is like using the reverse gear of your car to slow down, which no one does, which never works (because of possible breakdown of the engine) and should not be done to save the engine from damage. [ I am not a mechanical or automobile engineer. But this is my knowledge ]
- mhb 18y agoThe engine itself does not change direction. Surfaces are deployed to redirect its thrust forward instead of backward. And that is only done after the plane is on the ground.
- ars 18y agoThey have three things: Those surfaces as you call them. Thrust reversers (basically fins that push over the end of the jet and redirect the thrust forward), and the brakes on the wheels. All planes must (by FAA regs), be able to land without using the thrust reversers (using the brakes instead), but thrust reversers are what's used in normal cases (since it saves wear on the brakes).
- mynameishere 18y agoThey reverse the engines when they land. http://en.wikipedia.org/wiki/Thrust_reversal http://en.wikipedia.org/wiki/Thrust_reversal The wiki article on ditching is a little rough, http://en.wikipedia.org/wiki/Ditching#Commercial_aircraft http://en.wikipedia.org/wiki/Ditching#Commercial_aircraft ...but it seems like this procedure isn't done often enough with jets that we could honestly assess how difficult it might be. I suppose it's just like a normal landing, but doing it so gently that it doesn't break apart.
- JabavuAdams 18y agoUm. It's easier to go slow when you have no thrust.
- gravitycop 18y agoVery impressive how slow he got the plane to go. He used ground-effect to ride the plane on a cushion of air. http://news.google.com/news?q=%22ground%20effect%22 http://news.google.com/news?q=%22ground%20effect%22
