The 747, I personally feel, must be the most difficult a/c to taxi. The cockpit is so high up and it comes with small windows. Wonder how the tech crew feels when they taxi them in small airports. I read somewhere that Boeing actually build a contraption on the 70s to help pilots get used to the feeling of taxing up so high !
On a sidenote, does anyone know whether the B748 comes with taxi cameras(GMCS) ?
