I ain't missing nothin'. How much air have you got?  Hint: balloons fly because
they weight less than the surrounding air.

Helium, hydrogen and hot air balloons fly. Others just sit there.
The rubber is stretched until the air pressure inside plus the rubber
tension equals the surrounding air pressure.

True.  But simply because the pressure is equal does not mean that the *weight* is
equal.  I think you believe that I don't understand something about this, and I think
you're wrong in that belief.

As I said it is easier to hook the pump to the gyro.

Indubitably.
