Relatives of the AI 182 victims are still awaiting justice even after 21 years. It was on June 23rd 1985, AI 182 originating from Canada blew uo off Irish coast. Deadliest ever bombing of an airliner.
The initial Canadian criminal investigation into the attacks was marked by controversy, including charges that infighting between various branches of the justice system had led to the destruction of potentially key evidence.
Two men eventually went on trial for the bombings but were found not guilty last year after the judge ruled that prosecutors had failed to prove their case.
Canada has now opened an enquiry into the bombing.
