  It is shown that a model of a superconductor as a classical ideal charged
fluid at constant uniform temperature in a uniform compensating positively
charged background exhibits the Meissner state with the correct value of the
penetration depth. The differences between this model and the textbook
classical model that fails to predict the Meissner state are discussed, as are
the similarities of this model to the coupled Schrodinger-Maxwell model, which
does predict flux exclusion. In particular, this model does not neglect the
pressure term and terms that are bilinear in the velocity in the fluid
equations; these terms are essential to the results.
