Narrative:

During cruise flight at 35000 ft, captain's windshield shattered. Crew contacted maintenance control and dispatch via radio. Emergency was declared and flight diverted to chicago midway airport. Landing was made without further incident. No injuries or problems noted with passenger. No further damage found to aircraft. I feel this incident was a result of manufacturing defect in the windshield. I also feel that additional training should be given to crews in areas of how the windshield is constructed and actions to be taken should it fail. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a canadair regional jet and the windshield heat was on when the windshield shattered and impaired visibility. The reporter said maintenance replaced the windshield heat and the windshield controller and window heat operation checked ok.
