Today marks exactly six months since Ukraine International Airlines Flight PS752 was shot down by two Iranian missiles near Tehran. The devastating tragedy killed 176 people, including 55 Canadians and 30 permanent residents. It also left loved ones of the victims desperate for answers about what happened. Back in March, former longtime Liberal MP Ralph Goodale was appointed as special advisor for the federal government’s response to the tragedy. Today he explains why families are still waiting for the plane’s black boxes to be analysed, and what’s stopping the Canadian government from getting more answers.
