Because the tops of the wings are convex and the underside not (ie they have a D-shaped cross section). Air flowing over the curved upper wing causes a suction effect which pulls the plane up. If it stopped moving forward it would crash to Earth. Test this out by holding a spoon by its handle between finger and thumb and moving it underside first towards a stream of water flowing from the kitchen tap (faucet). The water wll pull the spoon towards it.
Planes can go up to the STRATOSPHERE.
the wing flaps go up and down
Most of the time, yes, but sometimes planes go west over Ireland.
They are actually called "planes" on a submarine and allow it to maneuver underwater. Horizontal "planes" allow the submarine to go up/down, vertical "planes" allow the submarine to go left/right.
Space planes will go up now that the space shuttle program was dropped. :(
Air planes can go up to 20,000 ft.
In the stratosphere,no clouds are present.so it is so clear to go up there.
Planes can in go in reverse on the ground with the use of thrust reverser's. Clam shell doors on the back of a jet engine that reverses the thrust and will actually back up the aircraft. All modern airliners have this capability.
Normal planes go at 40,500 feet from ground.
Not necessarily. A sphere is a "space" figure, but is not made up of planes.
they are planes that go above in the sky during war and drop bomb.....
the plane that was highest were the spy-planes 60,000ft!!
