The gigantic aircraft known as jumbo jets,
in addition to their 170-ton weight, are loaded with 150 tons of fuel.
With a maximum flying distance of 11,000 kilometers,
jumbo jets allow the world's cities to be directly connected.
Round trip travel from Tokyo to New York consumes
=5000eu 5,000 eu (per person).
A car (two passengers) and a jumbo jet consume
about the same amount of fuel !?
