12,000 gallons doesn't seem a lot ?
Imperial Gallons that'd be 53 imperial tons ? about 3 roadgoing tankers ? It'd need that much fuel to get any reasonable distance.
Would you refill it by flying low over a lake with a scoop down ? - not me mate
Surely you'd have to go to a big airport with a very high capacity filler upper (like the old steam trains used to have).
Must make it a lot less versatile that an amphibian ?
