Actually, the explanation I heard years ago is simpler. Remember that
in thermodynamics PV=nRT. Pressure is a function of the temperature
of a gas because the gas is exhibiting Brownian motion: following a
random walk/random collision trajectory at the molecular level as a
function of heat energy All you need is to have is the molecules in
a vibrating solid (solids are locked into place so they don't have the
freedom that gas molecules do) all decide to go in the same direction
at once: voila, the body is moving upward against the force of
gravity. When I fly I don't so much feel gravity cut out as much as
my body being pushed upwards.
