They are made of conducting material in order to earth it from (neutralize) any excess static charges accumulated on the plane's surface.
An inclined plane can be made out of various materials such as wood, metal, plastic, or concrete. The choice of material depends on factors like the intended use of the inclined plane, its environment, and durability requirements.
It was first made in 1940
The impedance of plane material is made equal to the impedance of air,in this way the waves sent by radar does not reflect by material of plane and pass through plane and do not come back to radar.That is why,plane remain invisible to radar.This material was invented by a PHD proffesor in UET Lahore Pakistan.

The material that the black box is made of is too heavy. A whole plane made of the same material (All stainless steel), it would have a hard time getting off the ground and would be ridiculously expensive.
In 1903 the Wright Brothers made the first plane. But actually before that Divinci made a device the flew. Though it wasn't a plane
Because it's the best material for the job.
No it was the wright brothers
in 1903
The Wright Flyer.
They made the first plane to fly in air in 1903.
