Airplanes are by default not in Minecraft.
To make an airplane you will need to download a mod.
You could probably mess around with command blocks, but it would take an expert to do it and a lot of time. Or you could download mods.
The easiest way to 'fly' without any mods is by choosing creative mode. Then, when you double tap the jump button (spacebar), you can fly and will not land on the ground
This is impossible without mods
You can download it of the official minecraft forums.

the life styles of birds are very good similar to the way of plane flies
You could make it so it looks like one or use the craft controller mod OR get a plane/zeppelin/helicopter mod.

I didn't make Minecraft.
The angle of elevation is increased as the plane flies closer because of the decreasing distance.
