Vintage plane's age not behind fatal Switzerland crash

Twenty people have died after a World War II vintage aircraft crashed into a mountainside in eastern Switzerland, police say. The plane - a Junkers JU-52 HB-HOT - was carrying 17 passengers and three crew on a sightseeing flight when it took off on Saturday. Operator JU-Air said it was saddened by the news and it had set up a helpline for relatives. It has suspended all flights until further notice. The cause of the crash is not known, but age was not an issue, experts say. BBC's Imogen Foulkes talks through the details with Susie Ferguson.
