Those nurtured by Czechoslovak TV can easily remind of Mr. Tau, a middle-class-looking hero of a comedy TV series in 1980s. He was even able to walk on a wing of a flying airplane! I am pretty sure that the constructors of Boeing and Airbus know him too, since they put warnings on an airplane wings: "Don't walk outside this area." Just look carefully on your next flight. No wonder if you meet Mr. Tau on the wing.
