Thurston showed that the total space of a symplectic fibration with a symplectic base can be equipped with a compatible symplectic form.  Here we first discuss the existence of compatible contact forms on such fibrations with compact contact base, and then study the tightness of the corresponding contact structures via Reeb orbits.
