A total of 20 people were killed in a sightseeing plane crash in the Swiss Alps, confirmed Captain Andreas Tobler, Head of Operations in the Graubunden Canton on Sunday. «There were no survivors to be found. All 20 aboard the flight were fatally wounded during the crash,» said Tobler. «It will take several days before the forensic analysis and identification of the victims can be concluded... Еще.» Swiss Safety Investigation Authority Daniel Knecht refused to speculate on the causes for the crash, but shared preliminary information. «It can be determined that the plane tipped perpendicularly and hit the ground with relatively high speed, said Knecht. «Today's temperatures are an impairment for the aircraft's performance. But it's never the weather conditions that are the cause of an accident, but the way they are dealt with,» he added. «Fundamentally there weren't the conditions there for an emergency landing. That would require a relatively flat angle and that wasn't the case here,» concluded Knecht. A total of 17 sightseers and 3 crew members, all aged 42-84 years, were on board the World War Two era vintage aircraft when it crashed into the side of the Piz Segnas mountain in the Swiss Alps.
