They don't actually defy gravity. Rather, an airplane uses its wings to 'glide' amongst the air currents.
It's a matter of Action=-Reaction. Because of the shape of the wings, most of the air will move under the wings, which causes the air density to heighten and the airplane will be pushed upwards. An airplane can rotate its wings, so it can choose whether or not it wants to go upwards or downwards.
Apologies for my bad English, it's not my first language.

Why do airplanes defy gravity?
Airplanes do not "defy gravity", any more than you do when you walk upstairs. In both cases, an upward force is generated that is greater than the downward force of gravity on an object. Since the net force on the object is then upward, the object accelerates upward.
Do airplanes defy gravity?
No. The wings are shaped such that there is constant updraft on the wings that holds the plane up so long as the forward speed continues above a certain level.
Do earthquakes defy gravity?
No
What is the plural of defy?
The plural of defy is defies. As in "this defies the laws of gravity".
Do magnets defy gravity?
Magnets do not defy gravity, but they can create forces that appear to defy gravity. When a magnet is placed near an object, it can create a magnetic force that opposes the force of gravity acting on the object. This can make the object appear to levitate or hover.
What chemical that can defy gravity?
The chemical that is called defying gravity.
Can light defy gravity?
Ultimately, no.
Why can gecko's defy gravity?
They cannot.
How does the anti-gravity wheel work to defy gravity and create a levitating effect?
The anti-gravity wheel uses magnets to create a repelling force that counteracts gravity, allowing the wheel to levitate and appear to defy gravity.
What is a good sentence with the word gravity?
The water seemed to defy gravity.
Would steam defy gravity in a vacuum?
No.
What makes the people defy gravity?
nothing
