CASS 2004 came to a successful close in Toronto on April 21, where nearly 400 delegates from industry and government participated. Delegates attended a very strong workshop program on day one, followed by one and a half days of presentations in plenary, by industry experts, on aviation safety and risk management topics. The emphasis throughout was placed on the continuing path towards the implementation of safety management systems (SMS). Several question and answer sessions allowed participants to discuss issues directly with guest speakers.
