Dryden Crash

Transport Canada is gradually implementing a safety management system in the aviation industry.

However, there are many critics.The former commissioner who investigated the 1989 crash that killed 24 people in Dryden is among them.

Virgil Moshansky says he sees similarities between now and events before the 1989 crash.

Transport Canada says the system offers an extra layer of safety.However, inspections have been cut and the unions say inspectors are being lost.
