quote "i was really amazed when i Antonov with its 18 wheels took off"
I believe that the Antonov has 32 wheels if Iīm not mistaken!
I once worked on loading two Mi-17 helicopterīs into an An-124 in Prague. They had 4 reserve wheels (tires on rims) with them. I guess taking a few extra wheels makes no difference in an airplane this size.
