What do You think: why do we want to fly so badly? Why did Daedalus and Icarus strap wings to themselves? Why did Wright brothers construct a plane? Why do we like to fly in lucid dreams? Why do we climb Mount Everest? What did we fly to the Moon for? Why there is such a psychological flaw in us? Why do we, land animals, want to be birds? I presume, we were angels once upon a time, but God took our wings back after the first sin. What do You think about this?
