French investigators have concluded that the co-pilot deliberately crashed the Germanwings plane into the French Alps Tuesday, killing all 150 people on board. German officials say there is no sign of any link to terrorism.

The authorities and people who knew Co-pilot Andreas Lubitz are at a loss to explain his actions.

The black box recordings indicate that the 28-year-old German co-pilot intentionally sent the plane into its descent into a mountain while the pilot was locked outside the cockpit, pounding on the door to get in as passengers screamed

The chief aviation investigator for the Canada’s transport watchdog says he’s absolutely confident in the safety records of Canadian airlines and the psychological testing administered to their pilots.

Mark Clitsome with the Transportation Safety Board says members of the public shouldn’t have pilot-related safety concerns in the wake of the fatal Germanwings crash in France.

Clitsome has spent two decades probing high-profile air incidents and says what happened on Tuesday was very rare and that Canada has one of the best accident records in the world.

He added that while he has faith in current protocols, he’s not aware of any cases where a major Canadian airline endured a similar incident.
