If you owned an airline, how would you want the public to perceive it? You'd probably want them to imagine it was glamorous, and luxurious, and efficient. Your marketing would feature photos and videos of your shiny new planes, soaring high in the sky. In short, you wouldn't do this.
We don't know which advertising salesman convinced Turkish Airlines that this would be a great idea, but they must have the best persuasion skills in the world. It looks like the plane is nosediving into the ground.
