Flight, weather it be a firefly or an AirBus is dependent on the thickness of the atmosphere. This thickness, or density of nitrogen and oxygen atoms
is dependent on the magnetic field of earth and how much it draws other magnets(atoms[atmospheric gases]) towards it. With sufficient density a wing
can apply force to the atmosphere and create movement, much like a fish uses its fin to apply force against the liquid water around it. Airplane
wings, like bird wings can create areas of low pressure above the wing and high pressure below, creating sustained lift as long as movement through
dense gases persists.
Not a total explanation, but I do have a child and a girlfriend who are desiring a lot of attention on my day off of work here.
