Superfast plane

Look at my Superfast plane! I drew it on a computer.  You will notice it is a double-decker plane like the Airbus A380.  But it also has huge area below the passenger decks to carry a lot of cargo.  And there is something else very unique about my large plane – It can land in water and take off in water as well!  Can you come up with another design?  Do let me know.
