the relevant factor in whether glass is a liquid or solid isn't whether it
flows or has crystalline structure or obeys euler's equations.  mechanical
engineers get around the problem by calling it a "viscoelastic" solid.  it
certainly is possible to have a noncrystalline solid and to have a fluid
which fails to satisfies euler's equations (which apply only to newtonian
fluids).
