Somebody said, if the normal capacity of a motor bike engine is to run at 40 Km/hr, is then fitted to a boat it can sail at 80 km/hr, if you use the same engine to an aircraft it will fly more than that. The frictional force is what reduces the capacity of an engine. (Theory of Newton :salute:, Buoyancy :salute:, Bernoulli :salute: says that).
(Experts may advice.)
Now I am looking the same in different way:
(1) A motor bike / Vehicle has got one axis freedom (say x axis) – they have to follow the road. So person diving
it called as "Driver".
(2) A motor boat has got two axis freedoms; ( X axis & Y axis) can sail on a big flat water surface, and 70% of
earth is water, So person sailing it is called "Captain".
(3) An aircraft has got 3 axis freedoms, ( X axis,Y axis & Z axis) can fly in a space of air around earth (100%),
person flying is called "Pilot"
But the toughest along all is 3 axis freedoms is without oxygen.
(1) Space crafts – Astronaut
(2) Submarine – Helm and Planesman, submarine Captain.
So what is the point????
My apologies if that sounds dumb

Actually reading an article on submarine, nothing else.
According to Newton's theory you need exact force to create movement of object not only on ground but also in air with varying ground speed! and coming to Buoyancy you should be as light as possible in air and Bernoulli's say that upon both newton and buoyancy how pressure should act! that's it these are the difference ;D
but thing is these variables are almost different in all land,air and liquid.
but still these theoritical values never applied to practical in aviation ! they will make some variations ;D
coming to space craft they use thrusters/propellent(made of apogee kick motor used in satellites basically )
and sub marines one heck of a good machine ! i got chance to travel in submarine once but its really good experience!
