30. Why are airplanes white?

Have you ever wondered why planes are usually white? The reason for this is that the white color absorbs less heat. It’s cheaper for airlines to go this way and it’s also better for passengers. The white color is also useful in preventing the plane from colliding with different birds. This is because birds can easily see white surfaces well so they never hit the airplane.

Also, with the white color, it’s easy to notice any scratches, cracks and other damaged areas that may bring about problems.
